The process was pretty straight forward. Panel interview with 4 others. They asked routine finance questions. Interview lasted roughly about an hour and 10 minutes. I received the phone call from HR offering me the position about 2 weeks later.

After a one-on-one first round, their super day was a very typical series of behavioral questions. There were also some technical ones related to the airline industry specifically on that last day. The other reviews here did a great job of highlighting the types of technical questions to expect. Behavioral ones are ones you might encounter anywhere (behavior in teams, how to handle deadlines, etc.)
