It's possible, but there have been issues in the past.
I'm not saying he's effed himself. But just because you're in phase two doesn't mean you've been hired if you're sitting on something odd. Frankly, up and quitting your job before being given a class date isn't the norm. Just my opinion. We could stop hiring tomorrow. Then you're really hosed. Happened to me in 08'. Hiring right up until..... We're not.
I hope it turns out well. Beers on me in BOston.
