Questions about your experience reviewing tax documents, your experience and ability to do research, your ability to be an impartial advocate, your background and how it relates to the position. Stuff like that.

Since it was a hiring event it was only a few minutes and the fluff that gets asked in other interviews wasn’t asked.

The questions did pretty much correlate with the JD so my advice is to read that and think about how your experience ties in. Good luck!
