Pretty simple process. I had a 45 minute phone interview with a recruiter that went through some behavorial questions and deep-dived into my resume. The recruiter asked a lot of follow-up questions about my experiences. Then, I had a virtual interview day (thanks, Covid!) with an hour long tour of the facilities and then one-on-one interviews with 3 other members. I had a virtual lunch chat with 2 people currently in the program. Overall, it was four hours straight of interviewing. They are looking to see how engaged you can be throughout the day, so be sure to ask interesting questions to your interviewers and definitely try to use up the entire hour or so allotted to each interviewer.
