The gouges are your best resource. I used mainly Compass and Delta gouges but I'd heard the old(?) ExpressJet as well. It is NOT ATP written questions! I also put a pretty detailed gouge for the cog test on airline interviews. Lumosity helps sharpen you up but definitely don't rush the cog. Do the practice for each cog, start steady, and as you progress through the task you'll find a good rhythm that allows for speed and accuracy. Then have some good TMAAT stories related to CRM and decision making. Good luck to those interviewing!
