I interviewed with two lab managers/directors though four were listed on the invitation email. They opened the interview by having me talk about myself and my background. Then they talked a bit about the company, the lab, and about the position I was interviewing for. They asked a couple of questions, then asked if I had any. The interview ended with me being shown around to the various stations of the lab.

Pretty short process once they asked for an initial interview. One video call with a supervisor and then an in person lab tour + second "interview" that was more just talking about my resume and going in depth about the position/company. Heard back in about 2 weeks for the job offer but declined because I got a better one.
