I'm doing this backwards.
I interviewed in April and am in the pool. At the suggestion of one of my interview "classmates" I'm checking out the forum. I did not have the advantage of reading through it beforehand. Its not necessary, but it sure is nice! I'm reading it now as I'm getting hopeful for classes.
Many folks have asked how long it takes to get the call. I first submitted my resume to Polar in 2007. I started getting serious with Atlas in 2011 by regularly sending resumes and such. Got the call March of 2013. Atlas is and has been my top pick and I'm happy to be given a chance to go there.
I can verify that the screening information and interview experiences posted on the forum are pretty accurate. I wish I'd known about them beforehand!
Best yet is the fact that interviews are happening again. That means the pool is getting shallow and hopefully we'll see classes soon! Best of luck to all.
