Pretty much what Herc said. I didn't have to do sim (121 qualified) and was offered S5 after telling them I wanted ORD as a base. Still took the Wonderlic test. 50 questions in 12 minutes. Obviously you can't finish them all but I would suggest getting through at least 25 of them. One dude who said he was on #19 when the timer went off went home after testing. 25 question technical test, easy. Get gouges of aviationinterviews.com and its pretty spot on. Good luck.
