If I remember right, you pay for the prep and get access to the audio files.

I did my interview prep with Emerald Coast (Albie) a few years ago. I cannot imagine what my airline interviews would have been like without it. I attended the seminar with a few other soon to be ex-mil guys. The effect of answering uncomfortable interview questions in the presence of peers added an entirely new dimension. Being honestly debriefed on involuntary nervous mannerisms or disfluencies in speech I was previously unaware of helped tremendously.
