I was contacted by a recruiter and went through phone and on-site interviews.

The overall on-site interview process was very lousy. There was significant confusion from the beginning regarding the exact timing of the interviews.

The main interviewer didn't show up on time, being 30 minutes late. Consequently, the shadowing interviewer started a question. When the main interviewer finally arrived, he showed no interest in the interview and acted like a jerk.

After the coding interview, there were a couple of system design interviews, and in the end, a behavioral interview. This made for 5 rounds in total, including the lunch.

After the interviews, the recruiter passed me at the door without the courtesy of saying goodbye and never contacted me about my interview results.
