Hi,
For IT consulting companies like Accenture you'll have regular cases (Market sizing, profitability, market entry, erc) plus the cases or questions related to strategy and Implementation:
- SAP implementation
- Servers structure
- Process automation
- IT strategy
For BIG 3 companies like McKinsey, that has a Digital department, the cases will be less technical like:
- Agile transformation
- Digital transformation
- Regular MBB cases
For the regular cases on preplounge will be most helpful. For the IT cases I recommend reading the articles of the consulting companies about these topics on their websites (Hundreds of them if you google by key words "agile", "Digital", at McKinsey or Accenture)
Good luck!
Thank you will look on that.
