If you've been following any of the other boards, you are aware of a very turbulent time at Atlas and Polar. With Polar on strike, now for almost two weeks, its starting to get uglier. Check out this thread on PPRUNE.

If you can fly the sim in a proficient manner (ie, don't crash), and can support your logged flying time (ie talk about some of your experiences), your chances are good. The interview is just general conversation and questions, non- technical. If you were called for an interview, they like what they see.
If you have some glass, you'll end up with a -400 type. I believe the sim eval is in the classic sim. Not real tough, T/O, a departure, a vector or two, and then a clearance to holding. Then vectors to an ILS to a landing. Another T/O and vectors to a VOR/DME approach and landing. They are looking for a foundation to build on. I have heard of some real horror stories. Guys that claim heavy time but can't even keep the shinny side up, straight and level.
If they are happy, you could get a class offer right there. I had friend interview on Thursday and get a job offer to start on the next Monday.
I hate to recommend another board, but asking on PPRUNE may get a better and more recent experience to work with. This is a new board with a limited viewership.
