Word on the street is that Cage Marshall is booked for months. Emerald Coast Interview Consulting has a good product but very little one-on-one other than 1hr telephone top offs. FAPA has a decent service. I'm not familiar with the other companies out there but the advice stands - some prep is better than no prep.

I do have friends that did not do any formal prep - they all got hired somewhere but not necessarily at their "dream job".
