Apparently it depends. I did not but I was able to use their online applications with no problems. My buddy couldn't get their system to work so he did most of the paperwork the hard way (hard copies, scans, email attachments etc). He got a completion email where I did not. But I contacted Sterling a few weeks ago just to verify and they quickly replied saying it was finished and submitted to JB. We were Mar 11 interviews.

FWIW, I know of another guy in Phase II who since interviewed, was hired, and has a class date with SWA. There is a really good chance that he will be close to done with training at SWA before JB calls him with a class date offer.
