Several stages of the interview process (various meetings with several current MAs and then a final meeting with the hiring manager). They were relatively short (only asked about 3 questions each time).

The whole process was relatively painless. There were two to three interviews and then a project. I believe the project was to create an infographic for patients. Interviews are pretty simple. I think they're getting a sense for who you are, how you work, and how you might contribute to a team dynamic within the office.
