Unprofessional. interviewer 5 mins late. completed coding in 10 mins and then he was general talking and then system design (even though it was not in plan). Interviewer didn't had grasp of the pb he is asking and i had to point out the issues. (kind of odd that interviewer don't completely the questions) even answering all the coding and details correctly, random rejection. I think they probably just window shoping. See the reviews.most have bad experience.
