Interview questions [1]
Question 1
Describe a difficult experience working in a group.
Two rounds. First with remote behavioral with a basic level remote case interview. Second with in person case interview, presenting a deliverable. About an hour long. There was help from Deloitte interview "Buddy".
First round consisted of one case interview and one behavioral interview, back to back. Each interview is scheduled for a 25min time slot. Mine was on-campus so you just switch rooms in between.

Interview
Very selective process, took 1 kid out of my entire class. Expect at least 2-3 interviews for each round consisting of case and behavioral interviews. This may vary by location.
