Hi there,

Caveat: This is my understanding from some research/googling.

Level 2 vs Level 3 in McKinsey's Problem Solving Scenario (PSS) interview refers to the level of analysis required to solve the business case.

Level 2 refers to an analysis that goes beyond surface level observations and requires a deeper understanding of the business issue and potential solutions. It requires the ability to synthesize information and apply frameworks to arrive at recommendations.

Level 3 refers to the highest level of analysis, where the candidate is expected to demonstrate not only a deep understanding of the business issue, but also an ability to think creatively and develop innovative solutions.

So when your interviewer says that the PSS will have a "depth on level 2, not level 3 as typical business cases", it means that the case you will be working on will require a deeper understanding of the business issue, but not necessarily expect you to come up with a highly innovative solution.

The main goal of the PSS is to assess your problem-solving skills and how you approach complex business situations, so be prepared to apply your analytical and critical thinking skills.
