University of Colorado interview questions

Two stages, 30 minute video interview with PI and a two-hour on-site interview with a few different people around the lab (fellow RAs, PI, and a Post-Doc within the lab.

The interviews were extreme, 3 individual video interviews after a phone interview. 2 months pass with no communication to receive an email with an offer. I was so confused, it seemed to me that they had offered someone else the position that maybe left abruptly and that’s only why they reached out. But no communication between.
