There was one day where suddenly I scheduled three interviews in one week, the first in three months. I somewhat panicked. I went to the library and pulled out a huge stack of books on interviews. Most of them were not what I needed - basic stuff like "what are you looking for in a new job?" - but this hit the spot.
The authors suggest you flip to the most relevant parts first, and I did. They talk about how to deal with illegal questions. They give suggestions. And, miraculously, it's not 100% focused on salesmonkeys. A great tips book, if that's the sort of thing you need.
