I interviewed at The Sainsbury Laboratory (Norwich, England)
Interview
This is specific to each group. It is pretty standard - scientific questions based on the role and lab expertise, lab tour, meet the team. A postdoc joined part of the interview.
Ad Hoc interviews. Was invited to the institute and shown around. Was a very good experience. Helped me formulate my views on the position. Interview was actually quite enjoyable, I had two very personable interviewers.
