The worst interview experience for me. These guys are not good interviewers and also they dont respect your time. I strongly advise against this company only because of crappy and unethical interview process. I spent 3 hours on this coding challenge and all i got that I did not use test framework for writing test cases. I did write test cases though. Just because of time I could not use test framework. This is absolutely insane. For other problem It was 10 lines of code and feedback I got was that I did not use the same function name which they mentioned in the problem description. Ha ha ha ha ha . WHy are you even working in here if you reject candidates based on such lame reason ? Anyways, even if people felt nice intially to me, I do not recommend this company to anyone. Looks like they need super engineers and if the speed which they expect in the interviews, if the all employees work at that speed then why they have not became google yet. Just attitude guys. Showing that we are smart and we dont want to hire you based on lame reasons. Advice to recruiting team: Please train your engineers on how to take interviews. STOP wasting time of engineers. There are 1000 other good companies so be respectful of time of other engineers.
