Malter1 I have to completely disagree with you. This isn't a check ride, it isn't a stan check, NATOPS ride, or whatever. If you are being interviewed then you meet the minimum requirements to pass on to the next step. But, and this is a big but, if you come to the interview and sound anything other than natural, I think that they will take the big pass on you. Not because you're not qualified but because they didn't get out of the interview what they wanted and that is very simply put, who are you really (or as close a facsimile as I can get in 15 minutes). Prep by all means, but if you give some guy 350 bones to prep you, you are probably wasting money for your SW interview. If it makes you feel better do it, but don't talk guys into it by comparing it to an annual ride. Practice questions with the wife with your buds but don't overdo it and don't think that paying for interview prep is required or even necessarily a good idea.
