I applied through college or university. I interviewed at Boston Consulting Group (Mailand)
Interview
BCG, as the other MBBs, use case interviews during their recruiting process. The process is very similar among countries, depending on the seniority. In Italy, count at least 7 cases, including an online case.
Interview questions [1]
Question 1

I applied online. The process took 4 weeks. I interviewed at Boston Consulting Group (Brüssel) in Dec 2018
Interview
Three rounds of interviews.
First round consists of computer test (analytical skills) and case interview.
Second round consists of 'in basket case' and case interview.
Final round is a single case interview.
In every round, the interviewers get more senior and more demanding.
I applied online. The process took 2 weeks. I interviewed at Boston Consulting Group (London, England) in Nov 2018
Interview
Both a 45 minute maths test and a 45 minute interview (with a personal and case interview within this). The maths test was very difficult, 40 mins to answer 20 questions. The interviewer really expected me to lead the case study, but was very kind. Expect to talk about failures as well as successes, focusing on team work/leadership etc.
