RE finance interview

I know there are many of these threads out there but I can't find any in a similar situation to mine...

in my early undergrad yrs at a semi-target, I have an interview over skype with a large repe firm with at least 5 directors / analysts... wasn't told what I would be asked. what should I expect? obviously have not covered any technicals through coursework and I really wasn't expecting to get an interview (got contacted months later), so not sure what to prepare. any help appreciated, thanks!
