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.

Question 1
HR interview is more about getting to know you and your capability in general. Senior management is to understand your past experiences and working skills. Not standardized questions.
