Building on the introduction provided during Alice’s PEI, Kevin introduces the PEI in a different manner by focusing on the overall format and structure of the interview.
By asking this broad question Kevin is testing to see if Michael can communicate, without prompts, those 4 specific attributes McKinsey seeks in a PEI.
By continuing this theme of questioning, Kevin is signalling that the initial answer probably did not provide the information he was seeking.
Kevin is focusing the discussion on neuroscience specifically around the data analyses part. Michael needs to demonstrate he can explain the logic and insights in his analyses.
