There were three rounds in the interview process. First with a recruiter, the second with the director and then the third with a member of the team. All three were straightforward. They asked me about projects I had worked on at my previous company.
Minium 2-3 interviews level dependent with a test to assess knowledge base relevant to role and department of choice. Process has been streamlined over the years I think making it a little easier.
Phone interview followed by in person interview with team. Questions about research and subject area in particular. Not difficult if you know what you're talking about. Would not hesitate to reocmmend.
