This type of interview questions worries me. My nervousness then permeates throughout the whole interview so I've never been asked these type of questions, which is unfortunate as perhaps it's not as bad as I make it.

Someone recommended Skiena's "The Algorithm Design Manual" and I picked it up. If you feel like more exposure to data structures can be useful, it has a section titled "A Catalog of Algorithmic Problems" which I find useful to read before an interview.
