Does anyone know what kind of case interview will be asked in the TEI - Technical round of the Mckinsey case interview? This is different from the PEI. This is for the role of a Data Scientist.

Any leads would be much appreciated.

I know about 2 different cases:

  1. Applying to McKinsey in-house data science company that they bought recently - QuantumBlack as an experienced data scientist. They tested the SQL requests a bit, but more thoroughly they tested the skills in Python programming and data architecture.
  2. Applying to McKinsey as a data scientist to R&I department as a PHD hire. The process was very similar to the standard R&I process at McKinsey. They usually ask the cases and PEI, but PEI is less structured (have 5-6 stories in mind and adapt them quickly). They also tested the specific knowledge of the industry in the PHD thesis for this candidate.
