Crazy enough after hearing nothing and our expiration date already passed, I received an email yesterday saying we had an interview date and time scheduled! In our case, the date is scheduled in early February so now we are scrambling to figure out getting to the interview and all that. I'd suggest getting all documents in order now and be ready with a plan on how you or your significant other will be getting to Consulate. I know it sucks because they don't really give you an option, they just say when it's happening and hopefully you can make it work.
