First round (Coding test): First round was the coding round on Hacker earth. There were 3 questions in the test for the period of 1 hour. The level of the question is easy to hard which means the first one is easy, the second one is medium and the last one is hard. I solved 2 questions out of 3 and was shortlisted for the next round.
