It was a whirlwind experience for me. As an experienced professional, the Case Interview is a different beast. Having done behavioral based interviews for my current company, Case Interviews are fun but challenging if you are not prepared. They give you a coach that preps you a little for the interview. Then the phone interview. It was a challenge doing it over the phone. If you or your interviewer doesn't articulate very well over the phone, then you are up the creek without a paddle. Overall, I wish I would have been able to progress further through the process but maybe another time.
