Strategy& Intern interview questions

Responded to an email sent by the career center of my university. Then i was invited for a round of 3 interviews, 2 with senior consultants and one with a partner. Each interview is around 45min with around 30min allocated to solve a business case. Some interviewees don't spend much time on personal questions, others focus more on getting to know you than on the business case. The whole process lasted about 2 to 3 weeks.
