I'm kind of in the same boat as you. Waiting on my BGC to get done though. My interviewer didn't tell me a start date, but we should be about the same at this point. They may be waiting for my group's background check to complete before they call everyone, so hopefully we should hear something this week.
I hope so... but I think about it like this- I'm almost a month and a 1/2 out from my potential start date, maybe they are waiting. Still, it would be nice to know what their intentions are. No news is good news I guess... lol
