Over the course of the case interview training program, it becomes very important for us to change our coaching style. First, candidates become used to solving cases in just this one style and we need to ensure they can adapt to any style. Second, candidates become adept at reading the "tell" in the coach/mentor so they know when they, the candidate, is making a mistake etc. By changing our coaching style and introducing mentors, we can easily avoid this problem and ensure candidates are becoming stronger at cases versus merely stronger at doing cases with the one coach. Ensure you are also practicing with partners who have different styles.
