I was very happy with the service I got from
Centerline, and was hired. The prep I got wasn't much about giving me the "right" answer, but about helping me dig out and properly deliver the best stories from my own past. It was helpful to shake the rust off and present well.
For what it's worth, I've been told multiple times by guys on the interview team that they can spot candidates prepped by Emerald Coast a mile away. Apparently they come across as very canned, and they don't like it because they aren't seeing the real candidate.
