I've been compiling lists from interview experiences and there aren't many repeated problems. I don't think this advice scales. However, I haven't seen any material that will teach you how to come up with the trick to cracking a problem you've never seen before. The best approach seems to be learn patterns and if you're stuck ask for hints. Doing mock interviews to get used to the format is also very helpful.
