My interview lasted about an hour. They were all or behavioral/STAR questions. Was asked about examples where I multitasked, dealt with a difficult situation, used unfamiliar technology, etc. There were a lot of questions so I would definitely have a set up responses prepared to common STAR questions. I was disappointed that I never ended up hearing back, even after emailing the interviewer twice. It's not great to be left hanging, but was a pretty fair interview and a great opportunity nonetheless.
