Informal and brief. Met the team and was more of a "get to know you" and "make sure you are someone who's competent and we can stand" meeting. Everyone was very easy-going and friendly. Got a followup email saying there was interest in hiring me and asking salary requirements. After my reply, I did not hear a response. I had to inquire with a friend who was working there what had happened. They had told the group I interviewed with that I did not like meeting any of them (not true) and was not interested (not true). I can only surmise that my salary requirements were too high and did not want to tell the team the truth.

Applied through a recruiter, took around two weeks to get an interview. Very relaxed interview with the Lab Manager and his boss. Took about 30 minutes just asking basic technical and personality questions.
