I had done my major in Science in one of the premier institutes of India. I had no background in Computer Science. However I had experience in competitive coding in platforms like Codeforces, HackerEarth, HackerRank, LeetCode etc. As I had to learn coding in order to get a job in a market like India.

Regarding the TCS Ninja exam details, I would always advise the Official TCS Ninja link with most of details covered on eligibility, test pattern etc. For practice questions, I would suggest review some of the usual topics that are part of the curriculum of Computer Science and Information Technology engineering degrees. Knowing multiple programming languages like Python, Perl, C, Java are very good but knowing a... Source: over 2 years ago

Also it seems you would enjoy the numer.ai stock prediction hedge fund tournament if you didn't already know about it. It's interesting not because of their token, and it's not about pump & dumps but because it's about providing actually useful stock predictions using machine learning models and getting rewarded for it. And you don't have to worry about the technical details of the trade execution on exchanges. So... Source: over 2 years ago
