Telephone interview, followed by on-site half-day interview with several people.
On the on-site day, the interview agenda had a lot of changes and shuffling. There was at least one interviewer who I felt was just killing time.
HR interviewer was very no-nonsense, and experienced. As someone applying for a role less than management level, I was surprised when I was ask if I would have any special requirements if I were to be made an offer (I didn't) -- I had never been asked that before.
A few of the interviewers were not experienced recruiters, and one seemed flustered due to an apparently busy day that day. I don't blame them for that -- it happens at a small'ish biotech company.
Everyone was friendly.
Despite being given the impression that the team was open to hiring people with diverse backgrounds (which, certainly seemed to be the case based on the backgrounds of the interviewers), I still got the impression they were looking for an (immuno) oncologist.
