Thanks to all you guys who replied to my original post. I wanted to give an update, too...I used the Airline Interview Prep to prepare for a regional airline interview. The airline I interviewed with was one of the ones listed as being one that the Prep works for. Thankfully, I passed the airline's written interview, but unfortunately, there weren't many questions on it from the Prep (almost none, in fact). So, even though, Sheppard says they have no guarantee or money back on the Interview Test Prep For Regional Carriers, I sent them an email just letting them know that maybe they should discontinue listing that particular airline as one of the airlines the Prep works for, and I explained my experience in the email. Sheppard couldn't have been nicer! They replied quickly and even gave me a refund! I hadn't asked for a refund or anything, but was just wanting to let them know my experience with the airline's written. Sheppard has really impressed me and I would certainly recommend to everyone to have no fear in using their programs. They are a more than fair company and have great customer service!
