Interview was a full day, 7 hours. Started off with a presentation of my own work followed by a series of one-on-one and group interviews. Prescreening: One phone call from the group manager. No technical content. Presentation: Almost no one came to this, there was an audience of perhaps 4 people, all of whom spent the entire time on their laptops. My work was not questioned nor were the topics I covered ever broached again for the rest of the day. Technical interviews: Simple physical concepts reviewed, maybe sophomore level of college. I was asked about. Lots of concerns/questions about being able to troubleshoot equipment and organize laboratory personnel. Behavioral interviews: Some of these questions were very straightforward. Why do you want to work here? What are your strengths? Etc. However, some of these questions led into strange and bizarre areas of inquiry. Overall, I found the interview was a strange one. The interviewers want to hear specific things in their answers and will sometimes lead and redirect until they get that answer...on both technical and behavioral questions.
