Started great and ended horribly. It all went well till assignment round until I was given an assignment with 3 hours length although it was a week longer if you try to finish the whole task. I picked up a part of it and tried to complete it. Then came the review round where two tech team members joined and they started reviewing and I started explaining and there was a part where I couldn't explain well my approach as I put that just as a normal thing without thinking much and interviewers even though understood that I am not able to explain the part well, kept on emphasis only on the same to the point where it looked like they are making fun of my knowledge about the subject and they stretched for 1 and half hour just to show their own knowledge on that topic just to reject me on a mail afterwards.

The hardest interview was behavioral. Most interviewees fail at that stage so prepare well. The questions are all standard and expected. JS interview was about a basic lodash like functionality implementation. React interview was about implementing a search functionality but the crux was about performance algo optimization via data appropriate structures. Both interviewers asked about time space complexity and both requested second attempt at improving your basic solution if not in code since little time will be left but in words. The deep dive was about picking some project from the past that you know good and diving deep into technical and architectural aspects testing your general understanding of how things work together.
