Overall it was a negative experience. I was referred by FOF, and I went till 2 rounds of interviews. 1) First technical round was consist of 2 DS problems , and one question on Java. 2) Second technical round was on System Design, the interviewer was not much of experience. Arrogant while talking, felt like taking interview unwillingly, just gave a problem and discussed over that, no introduction nothing. He just have gone through some youtube videos on system design and wanted the same answer from me. I have also interviewed people in my company till IIT level, never showed such rude behavior.
