I would almost be willing to bet that the people who made it through the interview are now just sitting on someone's desk, waiting for a final approval, and that person may not be in this week . . . or they haven't decided when to begin the next class, or something like that.
In my case, I was still flying corporate- calling my wife every day, asking, "Did AirTran call? Did the mail come yet?" and on my days off waiting for the mail, then going to the gym, then calling from the gym . . . then going home and pacing until 5:30 or so, and then and declaring it "Happy Hour" until the next day, when the whole think would start again!
When I finally got the call, I don't know who was happier, me, because I was hired, or my wife, because I could get back to normal (whatever that means!). Of course, just after I gave notice to my old employer, 9/11 happened, and I got to beg for my old job back and then repeat the whole process . . . which was only another 6 weeks!
Hang in there! As Judge Smaills would say, "See you on board, Senator".
