Dear all,
I am currently preparing for an interview at Roland Berger (German-speaking country). I read some Q&As but do not find a free website to train mathematical skills for this interview. Do you guys know in which depth I have to know mathematical calculations? And did anyone already have an interview at Roland Berger for an internship and could share how difficult the cases have been?
Looking forward to hearing from you!
Any information about the interview is highly appreciated!
