My experience with Coding Ninjas was fabulous. I took 2 courses from Coding Ninjas one is Competitive Programming and other for Machine Learning. The best thing I like about courses in Coding Ninjas is their content and faculty. The TA/mentor support was always a plus point as every time we are in trouble we can just ping a TA to get our doubt solved. After completing my ML course I was also selected to serve as a TA. Interacting with new students and resolving their doubts also made my concepts more clear.
The questions that were asked in the interview were mainly from Data Structures, Algorithms and Puzzles. Goldman Sachs always asks lots of puzzles in their interviews. Rest of the questions were from Operating Systems and Database Management systems. They also asked about the latest trending technologies and its impact in the coming years.
How did you prepare for the interview?
When I started preparing for my internship sessions, I found out that learning concepts from online free resources were time-consuming as the material as quite unorganized. Then I took the ML course from Coding Ninjas. It helped me improve my development skills. Secondly, it added a few good projects to my CV. Then I took a competitive course to brush up my programming skills. I made sure that I solve each and every question provided by Coding Ninjas as assignments. After that to practice more I used to solve on geeks for geeks and interview bit.
Advice to current students
The most important thing that matters is the clarity of concepts. Cramming things is not an alternative. The second most important thing is a practice which will make you more mature in finding the most optimal solution in less time. Before appearing for any company’s interview always have a look at their interview process and previously asked questions. One thing that should be clear is always keeping interacting with the interviewer else there will be a negative impact created for you.
How will you introduce Coding Ninjas to your friends?
If any students want a kickstart in their coding career, then one should take a foundation course from coding ninjas. It will help them clear their basics. The full-time Mentor support also plays a significant role in getting your doubts cleared and obviously the leaderboard always pushed to perform well.
My experience with Coding Ninjas has been wonderful. From being a student to being a TA to 2 batches and then being the Campus Ambassador and working with the Content team, the journey is enriched with wonderful experiences! Mentors that helped beyond imagination, one-stop solution to sparse and diverse material, a lot of dilemmas was resolved when I joined and gave me a good kickstart! A lot of memories made, I can surely say that Ninjas is home to me!
It mainly focused on Data structures, Operating system, Object-Oriented Programming concepts.
Advice to Current Students!
I work on the 70-30 rule. It means 30% theory of Data structures and algorithm and 70% practice.
If you are a student at Coding Ninjas, always ask your doubts. Even a single piece of doubt in any concept can be really fatal. So, clear your doubts and make your concepts crystal clear. Your teachers and TAs are there to help you 24*7.
Practice makes a man perfect is just perfect in case of programming, so practice as much as possible.
Be consistent. Even 5 questions every day can prove to be a crucial step towards acing in interviews.
Do not copy and paste code just to improve your leaderboard ranks. If you want to look into the solution, try to grab a pen and paper and try to dry run each and every step.
This will just embed the processing of that code in your brain and you will know how to solve that question as well as similar questions.
How did you prepare for the interview?
Aptitude preparation+ Data structures and algorithm questions that I did in Coding ninjas. Also, I prepared everything written in my CV thoroughly.
How will you introduce Coding Ninjas to your friends?
Coding Ninjas is not just a Coding Bootcamp, it is beyond that! The role it played in my life is irreplaceable and I can never forget all the experiences Ninjas has given me. I will simply say that Coding Ninjas is by far the best place if you thrive for knowledge and are determined to turn yourself into a Coding beast!
Coding — whenever you hear it or see how it works, it looks like some kind of alien monster that has come to haunt your life. Firstly, it is a ‘study’ — and we know how studying can be boring and frustrating. Plus, it has mathematics in it. And if all these doesn’t already make you feel afraid, coding is written in a strange language with brackets and semicolons and codes — half of which does not seem to make sense when you look at it suddenly.
But — we should never judge a book by its cover. Coding can actually look daunting, but behind all of it, coding can be amazing friend. #codingsedosti can be easier than you’d have thought! Now, how can coding be a friend? Of course, it is not human and you can’t share the human sentimentalities with it. But coding can push you in many ways just like a friend would do, and just like a friend sticks with you throughout, even coding is a #skillforlife. Here are some of the benefits of coding:
1. Increasing your creativity
As human beings, we are creative people. We are always trying to produce something of our own. And sometimes, when things are really difficult, we like to team up with friends to work on something special which we can all ours. In the digital world, coding is like that friend. Do you want to create your own video game? Do you have a plan for a new app? Well, coding is there for you. It gives you all the tools necessary to follow your dream and make your mark in the digital world.
2. Helps you to solve problems
Why do we have the proverb — A friend in need is a friend indeed? Well, a friend does not run away from a problem but tries to solve it for you. Coding may not solve your problems, but it will make you capable of solving your own problems. Much better, isn’t it? Coding helps your logical side and makes you more capable of breaking down a problem into smaller parts and tackle each part individually. Now, you can train your brain to find wholesome solutions to all your different problems in a jiffy.
3. Persistence Never Fails
Life is not something that will sway without obstacles. There will be many barriers and sometimes, those barriers cannot be overcome at just that moment. You have to wait patiently and persist of breaking it apart. It is here that coding can help you a lot. When you are coding, there will be several errors and barriers that you come across. But coding helps you to persist and try new solutions, new problem solving tricks to get it right. Persistence is the key in coding and in the world too.
4. Improving communication
How can coding improve communication? Well, think about it — coding helps you to solve problems by breaking it into smaller parts. Now, in case of communication, you can use the same tactic. Your mind is full of information and since our brain in complex and we have a tendency to overthink, the information stored in it becomes complex too. Coding helps you to pick out the simple information from this confusing sprawl of information and then convey it easily. A better communication means fewer rumors and better networking.
5. Critical Thinking
In the current world of the internet, you will come across many information and many opinions. Now, you can you single out a proper information or rather come up with your own unique thought? You can do it through critical thinking. It is very important to be a critical thinker in this time, and coding is just the thing that will teach you to do some. Much of critical thinking has to do with logic, problem solving and thinking out of the box. When you face barriers in coding, you have to be creative and think of solutions out of the box. But you have to pair it with logic to make it truly work. And if you already know how to do all these, then Congrats! You are on your way to become a critical thinker.
6.Getting Your Dream Job
A friend empowers you in many ways and what’s more empowering that making you get a job that helps you get settled in life? Coding will help you get the dream job that you want. If you become a master of coding, you have many opportunities in your hand, from big shots like Google and Amazon, to new startups coming up every day. Plus, coding will give you the power to say NO if a job doesn’t suit your needs. The choice is in your hands — now that’s true power.
Don’t be afraid of coding — make coding your friend. It will help you become a master of this world and the world of the future! And if you need a friend on this journey to befriending Coding, we welcome you to Coding Ninjas – where every concept is taken care from scratch, to ensure you only rise onwards and upwards!
If you are someone who wants to advance in the tech industry, then you know that there are a number of avenues that you can take. The industry is always bringing in new advancements and if you want to secure a job in Google or Microsoft, you have to keep yourself active with the recent developments. Web development is a very lucrative aspect which is in motion in the tech industry. There can be several kinds of web developers, but we will be talking about front-end developers — the individuals who code websites using building blocks like CSS and HTML. Web developers are growing in number and are in high demand, and that’s the reason why you need to be especially skillful to get hired by a company. Here are some of the essentials necessary for learning web development:
These are the first and MOST ESSENTIAL requirements if you are entering web learning. HTML or HyperText Markup Language is a markup language which is used to develop websites. However, while the foundation is built upon HTML, you need to look into the aspect of font, color and style of webpage. It’s here that the Cascading Style Sheets or CSS comes in to help your design a web page. Without the knowledge of CSS and HTML, web development is quite difficult.
There are times when CSS itself can be limiting — especially with regards to defining functions and variables. The problem multiplies if you are expanding. Hence, it is during these cases that this CSS preprocessors like Sass, LESS, or Stylus can be used. Here you can write code in the preprocessor’s language which the preprocessor can then convert into CSS-style code. It will make your job so much easier.
After all the hard work of presentation through HTML and CSS and programming using JS, you don’t want to start from scratch if you make a mistake. But if you there is an accidental mistake, you have to tear the whole thing down and start again. Unless, you are using Version Control like Git. Version controls tracks all your changes and if you make a mistake, you can go back to a previous version and make the corrections. With Git, you can create a “repository” with a hosting tool and then clone the repository. You can push the changes to your master branch. Since you are human, you can make mistakes. With Git, you can solve your errors easily.
Nowadays, we are using several platforms to open the webpage — computers, mobiles and now Smart TVs are entering the market. Webpages are not shown in the same way in a mobile and a computer. The adjustments happen due to responsive design. Responsive design is intrinsic to CSS but you have to learn it to be a master of how it can be implemented properly. You can use media queries to which will block certain CSS properties if certain conditions are true. Like for example, setting a browser window screen size and adjusting colour along with that.
You cannot just launch a web page without testing it first. There might be a number of bugs presents and so, you have to enter the process of debugging. There are two ways of testing: Functional testing tests the functionality of the webpage while unit testing tests every code bit. For developing a web page, testing is mandatory but the good news is, you can use programs like Jasmine or Mocha to simplify the process.
9. Building and Automation Tools and Web Performance
With GUI becoming the trend, learning command-line skills seems unnecessary. But this skill can really bring a difference to your skillset by giving you extra polish. While GUI will show you everything you can work with on the surface, typing out a command line by opening the computer terminal will be liking finding hidden items by digging into the surface. Command lines are still important in this period and gaining mastery in this area will make your web page development activity worth it.
So, learn these essentials of web development and become a tech master with a massive skillset behind your belt. Best of luck.
As a student, while reading for your exams, you may have been attracted to visual depictions of information. Flowcharts, graphs, pie charts, are still used for most statistics to give an overview of all the compendium of other boring data. Plus, in the age of the internet, infographics are getting viral like hotcakes. Data visualization refers to this representation of the information through diagrams or pictures. Well, now that we have the definition set aside, how can you make effective data visualization? Of course, you would need some available tools that will help you to design them. A designer cannot work without their tools after all. Here are some of the tools that you will help you with your data visualization process:
Imagine how difficult it would be to repeatedly format a design when you can just use a pre-set format. Datavisual, which was once private, became public and made the life of designers easier. Format your charts easily and coordinate large amounts of charts without facing any cluttering anxiety.
Referred as one of the masters in Data Visualisation, Tableau is simple to use and can create interactive visualizations. One of the best things about Tableau is that you can use it for Big Data operations too which includes machine learning and artificial intelligence. On top of that, it is integrated with a number of database solutions like Amazon, SAP, Teradata, and AWS.
Microsoft Power BI is one of the most efficient data visualisation packages present in the market. Plus, with the Microsoft tag, it can be safely said to be one of the most trusted too. It has two versions: Power BI Mobile and Power BI Desktop. It comes with a lot of custom visualisations as well as helps you create visualisations using many natural languages. Also, you have Cortana as your personal assistant. Microsoft Power BI is quite flexible too and connects large data sources like Excel, Oracle, Azure, Zendesk, etc. Plus, you get to integrate with web services easily as well.
So, engage your visualisation senses with these tools and start making sophisticated visual representations for your data. Present your project with a difference.
Oh, and talking about projects — you should check out our Data Science course. Designed to lift you up from ground zero, our course comprises of all the essential modules, including Data Visualization. We’ll also help you develop a project along the way!
Maybe from the time of its inception as a calculating machine which could also do a bit more — computers have made conspiracy theorists believe that it can replicate the human brain. With modern advancements, computers are becoming more and more complex almost like the human brain. The Turing Test is something every AI enthusiast tries to tackle — that is — trying to make computers exhibit intelligent traits that make it indistinguishable from human beings. But what’s the main difference between computer and the brain?
Like the brain nerves, computers also have a lot of transistors (which can seem like artificial neurons) connected to each other which receive and distribute information. Both can store data and reuse them in a certain way. But that’s where the similarities end. Computers are fed the information (meaningless for them) that they require previously and they arrange the information in a way that they were programmed to do. However, brains acquire information meaningful to them and can arrange them in many unusual, unknown ways, thereby ‘creating’ something. That’s the beauty of the human brain — they go through a slow process of learning how to use information and develop something new out of it.
However, neural networks are bringing a slight difference in the traditional pre-defined input-output scheme of computers.
Neural networks try to simulate the workings of the brain cells so as to recognize patterns, learn from it and thereafter, develop decisions based on them. Yet it is not as complex as the brain — it is made out of the same algebraic equations and mathematical variables that are put in the computer. The information remains meaningless to the computers, but for the people working on them — it means ‘progress’.
In a Neural Network, millions of transistors or artificial neurons are arranged in units and they are placed in layers as a series. Each of them are well-connected. Some of them are called input units. These units try to acquire information from outside and then use it to recognize patterns and different information from the outside world. Then, the information is sent to the output units. In between the two, there are hidden units with which the input and output are connected and these are the ‘artificial brain’. Each of the hidden units and each of the output units is fully-connected with each other and these connections are represented by a number called weight. The weight can be positive, exciting another unit, or negative suppressing another unit. This way, it reacts like the synapses of the brain.
One of the main requirements of neural networks is that it has to learn things. It is done through a process called feedforward network. When it is being trained or learning and then, after the training, operating normally, the input units take in the information, which is passed on to the hidden units, which in turn is passed to the output units. Every unit does not fire all together. Each input is received and then, it is multiplied along the weight of its connection that it is travelling along and when the sum is more than the threshold amount, it is triggered and sent forward. The feedback loop is important. Learning in Neural networks is through a process called backpropagation. Here, the output produced is compared with the output it is meant to produce. Using the difference, the weights are modified and the difference is reduced, until the actual as well as the intended output becomes the same. It is similar to how our brains react to feedback. As a bowler, if we throw a ball which moves slightly to the left of the wicket, in the next ball, we modify the pace in a way that it will swing to the right. Feedback loop and errors are the way in which both humans and computers learn.
However, computers deal with binary numbers and so, they will only have 0s and 1s as answers — that is, Yes and No. So, let’s say the difference between table and chair: if you input 25 different kinds of chairs, then the input have to interpret the item by posing different Yes/No questions to it. Does it have a back support? Can some sit on it for a long time? Does it have upholstery? Does it have a top? These questions may even help it understand that a sofa is also a chair — as it belongs to the same category, and that it is not a table.
Neural Networks — Uses
Neural Networks are being used in several places. Firstly, since it’s based on patterns and numbers, it can be used for autopiloting planes and for industrial manufacture where the right amount of formulaic ingredients will produce a product with predefined consistency in terms of colour, shape and weight. For checking the patterns of ‘credit or debit cards’,Neural Networks can be used. But the neural network technology is making its move in many areas. Voice recognition apps use neural networks to differentiate between email and spam. Even translation programs use neural networks to translate sentences, with Google using Neural Machine Translation from 2016 to convert entire sentences and facing 55% reduction of errors.
If reading the above spiked your interest towards technologies, coding and such, we recommend you drop us a visit at CodingNinjas, where we’ve got you covered!
In the digital world, coding has become almost a mandatory skill for everyone. But the term coding makes you a bit afraid, doesn’t it? At first, it might sound like strange numbers and characters typed on the screen. Then, there is the maths. Everything combined makes it appear like the devil.
But that’s just a myth. Coding can be very easy to learn and it becomes even easier if you start early and learn it from a young age. It’s one of the #skillforlife that will serve you forever. Here are some of the reasons to start learning code early.
1. A New Language
In India, most of us speak at least two languages. And if you think back, you might recall speaking and learning these languages from nursery. Why is that? It’s simple — language opens up new channels in our brains, and slowly builds up new patterns. Have you ever wondered how easily you can shift between your mother tongue and another language (say English) without faltering (Mini-tidbit: It’s called code-switching). Programming language, as the name suggests, IS a language. There are special characters like 0s and 1s and like every language, it has rules and directions too. So, open up the ‘coding language’ channels in your brain and start communicating with your computer in a special language.
2. Becoming Creative
If you thought that only artists and writers are creative, then you haven’t explored the world of coding yet. Creativity means the act of creation — the process of developing something. Coders are developing apps and your favourite video games, they are learning ways to prevent a mistake and they are always making updates to improve your experience on apps. Aren’t all of these a way of creativity? Coding is always involved in creating something new!
3. Problem solvers
When you come across coding, you will make mistakes. There will be obstacles. But coding teaches you the great #skillforlife of finding a way out. There will always be some problem in your life. Problem-Free life is boring. Rather the best thing to have a life where you have the skills to tackle every problem thrown at you. That’s what coding teaches — turning failures into success — making lemonade out of the lemons life throws at you.
4. Easy Maths
Many teachers may have told you Maths is not as difficult as it seems. But that’s not how it looks ever. Well, the reason is Maths deals with abstract concepts and these are something the children fail to visualise. Coding gives you the ability to visualise abstract concepts and make maths more creative and fun. No more wrong answers, no more boring Math problems which make no sense.
5. Finally, An Overall Academic Growth
Well, after all the different advantages, coding will help you in your overall academic growth. With your problem-solving skills and creativity, now you can come up with new solutions to your problems. Definitely, a #skillforlife but also useful for academics. Then, there is a boost in mathematics. Another hidden thing that coding teaches us is to structure and organise our thought processes. Discipline your mind and nothing that you study can get away from it. Academic excellence is within your grasp.
On top of everything else, coding is intrinsic to one of the most lucrative fields out there — the STEM field. So, why not start early and make the most out of it? After all, it’s a #skillforlife that will help you out forever.
A great learning experience for in-depth knowledge of programming!
Her amazing experience and what she loved!
I had a great learning experience with Coding Ninjas. The course structure was excellent and covered most of the topics which attracted my attention. The videos were perfectly divided, and each of the faculty members, especially Ankush Sir, did a great job taking each subject to a high clarity level.
It consisted of 3 rounds which revolved around concepts of Data Structures and Algorithms. The selection was also based on my resume and the projects that I worked on.
Advice to Current Students!
According to my interview experience, handling the edge cases is the most important factor taken into consideration by good companies. Interviews are not about complicated problems with exceptional algorithms behind them, but around questions which have primary data structures usage, therefore the most important thing has excellent clarity in DS.
How will you introduce Coding Ninjas to your friends?
I would definitely recommend my friends to join courses from Coding Ninjas for in-depth knowledge of Data Structures.
Selecting the right company that will appreciate your coding skills is something of a headache. Plus, there are so many coders out there and according to some, the industry is saturated. What are you going to do? First, remember, that nothing can get saturated. If you are the best at what you do, you will always have a place in the job market. And secondly, prepare for the top tech giants who are looking to hire more people in the near future. Here are some of them:
Well, one of the internet kings is always looking for top talent and India is a place they love to search for it. As Google holds Android and Android is always going through some kind of updates, Google loves to hire Android developers. Along with your general English skills, Google will test out your Python, C++, C, .Net, HTML, Networking skills, etc., drawing up the best skill set out of you.
Yes, the genius social networking site that is taking the world by storm — Facebook is going to hire a few people this 2019. With Facebook making more advancements with People, and AI bringing in its People-recognizing skills, the top skills that Facebook requires are Pattern Recognition, Data Structures, and R. Plus, they are prioritizing on Privacy everyday, so keep your security skills up and running.
The world of Amazon continues to grow worldwide. People are slowly moving away from traditional marketing to online markets. And you can also say Amazon is an e-commerce King. But Amazon does not only satisfy its customers, it satisfies its employees too. It recently increased the minimum wage of all employees to $15 per hour and they are planning on more expansion too. Brush up your AWS and Solution Architecture to get a secured spot in this wonderful company.
The premium brand is always looking for some kind of innovation in their iPads, Macs, iPhones and other appliances. No wonder that they are focusing on Machine Learning and Python. Glance through your Matlab to ace their interviews. Apple is planning to create about 20000 new jobs and are also wants to breach the Indian Market. Keep your shirts tucked in for the interviews.
Though one of its top locations is in San Francisco, Oracle has most of its employees outside San Francisco. They even have a niche towards India and the developers that they find here. Of course, they have their own Oracle Cloud as one of their top skills but along with that, you need to be well-versed with Python and NetSuite to make a place here.
So, find your place in the right company and give value to your coding skills. Remember, coding is a talent — you need to learn to use it well. And you need to go to the right place which appreciates and help you to grow that talent. And if you’re looking for mentors for this journey of yours, we invite you to Coding Ninjas, where we offer courses on multiple domains — each of which is likely to interest the giants mentioned in the list above!
There are always some kinds of changes happening in the world of programming language. Either a new language is introduced or a new language gains a lot of prominence and beats over the dominant one. There is always a push and pull — a power struggle. Eventually, this struggle defines the trend of the year. This time around, the trend will change from 2018. These are some of the programming trends that might conquer 2019:
Python has been among the top 5 programming languages for quite some time now. But now, the interest for Artificial Intelligence is on the rise and this, naturally translates to the increase in the demand for Python. Since, Python is quite the power multi-purpose language and quite easy to use, it is not a surprise that it is making its mark in the programming field. With Python libraries being available in machine language and statistics, it is turning out to be quite an attractive language, even better than R. Python is being used to make games, businesses, websites, etc. It might be ruling the programming market in 2019.
2. Typescript Will Become One of the Top 10 Languages
Kotlin has been a language popular among Android app developers. It is like Java and has interoperability with Java, it removes the null-point errors that Java is notorious for. Fast and error-free programming make Kotlin a favorite of many, and since, it’s popularity continues to rise, we might see it becoming more flexible — switching between functional to object-oriented and then, to different other platforms.
R is earning some much-deserved praise being the only language used for data analysis. It was developed by statisticians and scientists, and hence, it already has a niche market among data analysts, who prefer R over Python, especially for enhancing machine learning capabilities.
7. Full-Stack Programmers Will Get A Huge Popularity
Keep yourself informed and start planning about the future based on these trends. Remember, the future is always changing. You have to change your plans with it. And with that in mind, let’s tell you that Coding Ninjas offers courses on everything you’ve wanted to learn — be it coding, web development, or machine learning.
