So i decided to talk a friend in the recruiting dept here at GoJet, and here's the latest info on the flow.
We started sending pilots to spirit Nov 2017, there were NO classes in Dec:
10 pilots have gone to training so far
11 pilots are on deferral or the recruitment department is waiting on final application submission.
These pilots have had to interview and pass a talent assessment test for Spirit, new hires after the program was started need not interview.
Seriously guys, if you want to know anything about the flow, just talk to the recruiters. He stressed that nothing is a secret about the program and to feel to talk to even the head of recruiting.
