Two that might be helpful for airline interview prep are:
Checklist For Success by Cheryl Cage--this basically tells you how to not look like a goober during your interview, but it's still good.
Airline Pilot Technical Interviews: A Study Guide by Ronald D. McElroy--this goes over the most common tech questions at regional & major interviews (FAR, Wx, etc).
Both are by Cage Publishing and should be available on the internet somewhere. Someone might have already recommended these, as I didn't do a very in-depth scan of this thread so far, but they should help.
And for non-aviation reading, anything by Tom Robbins (with the possible exception of Another Roadside Attraction.)
Take it easy,
