Strategy interview at an investment bank

Hi

Does anyone know what is asked in an interview for a strategy role at an investment bank (Capital markets and Investment Banking space). I am aware that such divisions are rare in banks. However I have an interview scheduled with one of the big banks for their in-house strategy team. They said it will include a case-based round. Does anyone have an idea about what these cases are like or any experiences from similar interviews in the past?

This in house strategy team works with different desks of the bank and advises them on steps they could take to ramp up their business or cut losses etc

Thanks
