First of all, the recruiter forgot to send me confirmation link for my interview, next, the interview format changed from video to phone an hour before scheduled time, the scheduled interviewer was also changed. He didn't sound very prepared and it might be that he was put on the spot in the last minute. Most of the questions were pretty basic. I knew the answers to all of them, but received rejection email the very next day.

It was pretty doable despite the pressure, technical covers a case, behavioral covers who you are. In the case they expect you to show your thought processes and how you would tackle the problem at hand.
