BAT Analyst interview questions

Starting with a interview with a hiring company (classic/good one), then I had to pass questionnaires (SLR). After interview with an HR and then with the n+1. The last part was an assessment test : you have one hour with about 25 pages about a case. You have to make a little presentation after in 15minutes about the case, saying if you're agreeing or not, to launch or not, etc. And then 15 minutes, very challenging from the jury (3 persons).
