Most extensive interview process I've encountered and I've done a lot of interviews for consulting firms. 4 rounds: 1. HR phone screening, 2. Behavioral + Case questions, 3. Take home Case study (you need to make a deck based off the assignment they give you, it take 8-10 hours), 4. Superday (Behavioral, Consulting Case Study, Assignment Overview)
Made it to Superday however it felt like during the interview process, they let most people pass stages 1-3. Then on superday is when they actually start getting selective. Overall it was way too extensive for a position that only requires 1-2 years of experience and pays only 80k. However the interviewers were all really kind.
