The questions were pretty standard. I had a phone interview with someone from HR, also phone interviewed with the boss of the department I applied to join, then went for a face-to-face interview and met another member of the department. I also had to take a skills assessment test, which took about 20 minutes. (They sent a link and I took it at home.) It was all pretty casual and gave me plenty of opportunity to get to know the people I'd potentially be working with. I was happy to accept the offer, and so far haven't regretted it.
