I applied online. I interviewed at Boston Consulting Group (Londres, Inglaterra) in Nov 2019
Interview
Interview process was smooth, consisting of a maths test and then two rounds of case tests and personality interviews. Last round consisted of a 3-hr long case test and two interviews.
Interview questions [1]
Question 1
Case prep involving petrol stations pairing up with supermarkets in Portugal in the 1990's.
Very intense case interviews, usually run by a project leader or senior analyst. They will ask you a lot of questions and follow up questions. Be prepared! Most of them are nice, not all, so be ready for a tough hour.
Case study and personal experiences. They give you a lot of material to prepare with, it's a lot about structured thinking. Make sure you prepare the case study structures and know what experiences you can use to answer.
They were looking for someone who would be willing to jump in to multiple roles, not just the one advertised and the pay did not reflect my expectations for the level of work they wanted.
