@Parahawk-
I'd just be as honest as possible and tell them the details about the misdemeanor. Sounds like it occured when you were young (and stupid? lol) Since I assume you have a clean record from then just chalk it up as a learning experience and move on.
I brought my wife with me for the interview. It's been her dream since childhood to visit the M.E. so of course she loved it. And of course I let the recruiter know the Mrs. was on board
We did some sightseeing/shopping but that's about it. No kids so we're not concerned about school. We've been looking online at places to rent and will most likely consult a realtor once I'm in Doha to help us find a place.
