I had my interview last week. Drove 6 hours to the city in which it was hosted and two hours later drove back for another 6 hours, all in one day.
Maybe this will help someone else:
Questions I was asked:
-Why HEC/ESCP/Lyon and not the other 2
-Why France?
-How did you end up at your alma mater?
-I see you have so and so listed as your interests, these are quite unique, how did you become interested in these?
-You don't speak French, how will you handle this?
-What kind of a track are you planning on doing?
-Why not a different one (Sports Management) given you background (athlete)?
-What do you want to do with this degree?
-Next couple questions focused on the answer to the last question.
Finally,
-What do you know about French people and France?
-Can you talk about some current events
-In one sentence, tell us why we should put "Excellent" in every category in our evaluation of your candidacy
Overall, there were 3 people present and about 7-8 candidates. The email says it was supposed to be Business Casual, but everybody was Business Formal. My interview was more of an interrogation, but that's because when they asked me what I want to do I screwed up. I knew exactly what I want to do with the degree and what my career plans are but I started overthinking it and for some stupid reason deviated from that and didn't come across as somebody who knows what they are after. Can't do anything about it now and I tried controlling the damage as much as I could, which seemed to work to an extent, generated a few laughs and we moved on. It'll be a miracle if I get admitted to any of these, but overall it was a great learning experience.
Make sure you have your story in and out, know whats going on in the world and be able to express your motivation for attending these schools. Be also prepared to be put on a defending stance and come up with examples relevant to the problems the committee will be trying to throw you off with i.e. "You've never been to France, what can you possibly know about French schools?".
Just answer as diplomatically as possible, throw in some evidence of overcoming similar challenges and express your enthusiasm and you'll be fine.
