two interviews, first with HR asking general questions ( what salary and check I have skills for the job) and second with the hiring team (it was a Competency Interview question; 4 questions that I needed to give examples and the questions were not easy questions

First, there was a 1 hour interview with 2 managers, asking about resume and some behavioral questions. After that, the 2nd round was 4 hour interview with 6 people and one seminar with research talk. It was quite pleasant.

Met with recruiters on campus after a quick introduction at a career fair. They asked me some questions about my experience as well as a few behavioral questions. They then told me about the location and position in more detail. I was then invited to an on site interview which took almost a full 8 hours. I met with 10 different employees who ranged from easy going all the way to curmudgeonly old farts who asked trick questions so they could see how you react under pressure.
