Behavioral questions. All situational. First phone screen, then hiring manager interview, then a loop with 5 people interviewing (1 hr each) in one day. The most difficult part was the last day which was quite tiring.

Two phone screens - one with hiring manager and one with someone on the team. Led to in-house interview day (about 5 back to back 45m interviews), including the person from my phone screen again. Questions were all behavioural in nature. As long as you have lots of experiences to draw from and the detail of the things to did in you mind it's not difficult. Whole process was extremely unplesant bordering on hostile. No time to ask questions, got no insight into team culture or what future colleagues might be like - actually disliked one interviewer so much and his aggressive style that I turned the job down in the end. Rudeness is never acceptable. It was clear that if that is how they interview, it was going to be an unpleasant place to work. No one I interviewed with seemed to really care about me at all beyond ticking a box. Just a really soulless experience. I've worked at plenty of large prestigious companies and never felt as disgusted walking away from an interview day.
