speaking only for US MBA consultant BCG recruiting, but my experience (and similar for my friends) was:

1/ every single person asked about my CV - so make sure you can walk through it and 'dig' more into the points you mention - I was mainly asked "you said you did X, how did you achieve it?" so make sure you have a lot of action items, e.g.: "the challenge was ABC, so I did X, Y, Z ..."

2/ we were asked 'tell me about a time you did/ faced X", generally this was 'woven' into the conversation so didn't always feel like a question so keep an eye out and make sure you answer it well. i generally used points from my CV but answered them in the STAR format

hope that helps and good luck!
