@alezozov: many congratulations on the interview opportunity. I would suggest the B1/B2 visa used for leisure-tourism and/or business. Ideally, if you can get a multiple entry visa valid for a few years, it would enable your visit for the interview, as well as a stay for three-odd months during the Winter session as well. That said, USCIS tends to be dodgy and unpredictable about these matters, so fingers crossed on that one. All the best!
