5 rounds in one day including behavioral, coding, and technical round. In coding round they asked for backtracking question, and in technical round asked what are my technical background and then dug deep into them

I received a computer and coded a problem they gave me. Remember that uncomfortable feeling when in high school you took an exam, and the teacher walks up and stares at your paper? it was like that the entire interview. The interviewer started at my computer and watched my code, and didn't say anything. I felt highly uncomfortable and creeped out. I would much rather have an interview on a whiteboard - which is more collaborative; or coding and later being reviewed.. rather than someone silently glaring at you and every single word you code. In the end, he felt I didn't have enough experience, and it was something he could have known if he looked at my cv before, or asked me in the phone interview. The entire process was disappointing, add to that the creepy feeling all along. My advice, if you come over for an interview, make sure they read your CV so you won't waste your time.
