Whole thing took around 3 weeks. There was 4 interviews, with each getting harder and more specialized/specific. They asked some questions about web pentesting and binary exploitation. The interviewers were very nice and professional.

Went through a few phone calls. Ultimately was rejected for not having enough experience. It was very hard to contact my recruiter, and I would not receive any responses. The interviewer was friendly but it was evident in the interview that they were not interested from the beginning.
