Competitive Programming

Competitive programming is a mind sport usually held over the Internet or a local network, involving participants trying to program according to provided specifications. Contestants are referred to as sport programmers. Competitive programming is recognized and supported by several multinational software and Internet companies, such as Google and Facebook.

Where you should start (Am not advertising for any of the platform)?

If your just a student who is just entered engineer or any graduate in any stream interested in coding (learn the fundamentals thoroughly = Data Structures) . After your done with or in progress of this start your coding journey with Hackerank.

Hackerank

Hackerank has wonderful way of setting problems from the basic level to the moderate questions . For example : 30 Days of Python (Note : other programming language )topic presents you problems based on the basic fundamentals of python . Which will be helpful to brush your skills.

Hackerearth

The User Interface is bit different in this. This has wide range of questions on each topics like Arrays ,Strings with simple basic level programs for a beginner to catch hold of the DS & Algo concepts correctly.

It will help you tackle the interview questions with ease.

Basic Criteria

You should start with a programming language and I assume you already know little bit of C, next come the Data Structure and Algorithm analysis and designing. The best source is possibly ; GeeksForGeeks.

Start with Hackerank then proceed to Hackerearth and Leetcode then the icing on the cake Interview bit.

These websites are not designed to prepare you forgetting jobs. They help people get better in competitive programming. The problems are complex DS ALGO or MATHS based problems, most of them would never be asked by any interviewer. However, solving such problems helps to improve your thinking abilities and you can tackle a problem from many different angles.

If you want to get good at competitive programming you can practice at any of these sites but if only a good job is your concern you don’t need to. For getting a job, you can start practicing at interviewbit.com. It contains all the standard problems on almost all the topics that are asked in the interviews. You will get nice questions on DS and some algorithms as well. Plus, you can code and submit using their online IDE and get points for it.
