I did the assessment last fall - I was really really straightforward. 75% personality stuff, then some conginitive finish the pattern or spacial reasoning multiple choice questions. I didnt do any prep or any secret method of choosing my answers. Got invite to interview about half hour after sunmitting it. Do whats best for you. If you've been in the game for a while, the way I look at it, Frontier would be much better than boppin around a regional, but thats just my opinion.
