Had a message this morning from Atlas. I had passed the online test in early October. The message said the call was to "go over my resume" which I assume is the phone interview.
No idea why it took almost six months from test to call. I had been pursuing Atlas since late 2012. My quals are ~11,000TT and CL-65, B757, & B767 type ratings. Worldwide part 121 in the B767.
Anyway, don't give up if you don't hear anything right after taking the online test. The timeline is apparently quite flexible at that stage! LOL
FWIW, I started with United Airlines earlier this year so I won't be doing the phone interview. I received the invitation for the online test last September about a week after the email that started the UAL process.
