A 15-minute phone interview was followed by an email invitation for a technical interview. The technical interview process lasted four hours, with a 10-minute break in between. Overall, the process was well-organized and straightforward.

On-campus interview. He asked about the projects that I've done in the past (very detailed) and there's a simple delete duplicate in array coding question.

The people were very nice. They offered water or tea at the beginning. Later on, I even got a refill on that (water). All in all, very nice.
