I was contacted by email from a recruiter. The recruiter had a list of questions that they wanted me to answer. The next day I was asked to schedule a in person interview. The interview was with two people, it was very relaxed and felt more like a conversation than an interview. At the end of the interview I also received a tour of the lab.

Standard interview. Asked for scenarios or examples of "times when...", etc. Asked about previous employment, strengths and weaknesses, why I'd be a good asset to the team. Interview included a full tour of the facility and the job functions, which was very helpful in deciding if I wanted to take the job.
