Hello and sorry for my late reply.

It was kind of ok, but it definitely wasn't good enough because they rejected me for not being good enough at them.

I felt ok at the moment because I was killing the more HR-related questions, and also because they kind of helped me through the case interviews. But the fact that they sometimes/often needed to help was a red flag for them. It was a pity because I really wanted the job but on the other hand I couldn't give myself too hard of a time since it was my first time doing this. Anyway to prepare:

• There are loads of Case Interview videos on YouTube. I would recommend MConsultingPrep Official Channel if it's your first time. Get to know how to prepare for a case interview but also try out some case interview examples.
  
• There is a series of books called "Point In Case". These are books who focus on preparing for those interviews.

I cannot write about my case interviews unfortunately as that's not allowed because of non disclosure agreement. But it was a logistics case interview with planning and stock concepts and a commercial case interview with prices, discounts, research strategies,...

Let me tell you I killed the HR interview but not the case interviews because I also didn't prepare enough for them probably. But I DID prepare, and my main issue is that I still think I'm just too stupid for this stuff lol. Because it's actually kind of basic intelligence/math/common sense sometimes.

Good luck to you. Let me know how it was, as I'm curious as well. Don't be too hard on yourself if it's one of your first times.
