There was a phone interview, followed by 4 separate in-person interviews back to back. Each one had a different role in the company including Operations, HR, Customer Service, etc. I also had to complete a math flow question and wright a few short case study question responses, which were reviewed with me during one of the interviews.

Pretty easy and straightforward if you follow the STAR method. Have a lot of examples whether real or made up to support your answers. They will send you an FAQ for interview questions and it was helpful
