I have an upcoming interview for intern position at Boehringer Ingelheim (Pharma Company HQ in Germany) in Internal Consulting. The interview is planned for 30 mins and I did not receive any notice about case study. I am still unsure of what to expect? I checked their website and the interview questions on Glassdor, but didn't see any mentions about case interviews within this company. Do you think is possible to have a case interview without mentioning it?
