Bain Future Leaders Program Coffee Chat

So I did some searching on the forum and in general through google and couldn't find out much at all about this program, perhaps it's new.

So I applied to the Experience Bain scholarship, and just got an email I'm a finalist for the Future Leaders program. If selected I'll be matched up with a current consultant for mentorship. Maybe a soft ding from the Experience Bain scholarship that they offer to everyone, I'm really not sure.

So they also said I have the opportunity to do a virtual coffee chat next week. I'm a career-switcher starting an MBA at one of the M7 schools next fall with zero consulting or real world business experience so this is all knew to me.

The email doesn't say whether it's one on one or with a group, only that it's on google hangouts. Since I'm totally new to this what can I expect from the coffee chat? Is it just a more casual conversation or should I prepare like I'm going in for an interview. There's no way I can prep for a case style interview in time (only have a few days and I'm starting from zero) but should I just review all the normal behavioral style interview questions? Any other advice? Thanks in advance for any help
