Case Behavioral Presentation
Super quick process, wrapped up in about 2-3 weeks. Started with a call with HR, then two back-to-back interviews with consultants, and finished with an interview with a Partner. The interviews focused on classic consulting case questions, including both fit and a case study.

Behavioral Case
I applied online. The first round had two 30-minute interviews, with 10 minutes for behavioral questions and 20 minutes for a case (for consultants). The final round had three 30-minute interviews, with 10 minutes for behavioral questions and 20 minutes for a case (for managers and above). Everyone was nice. I thought the final round went well, but I didn't get an offer. The cases were standard, and one in the final round was focused on business logic/acumen, without a matching component and less structured.

Technical Case Behavioral
It started with an online test, then a GMAT-style test. After that, I had two 45-minute interviews with associates and senior consultants. It was a blind interview, so they didn't ask about my CV. There was also a 15-minute break where I spoke with another associate and could ask them questions. I didn't make it to the next round, which was disappointing because I wish they had provided feedback to help me improve.
