I agree that the puzzles are bad interview questions. But if you want a _specific_ job, it's always a good idea to find out about the interview culture (if you can, it's almost impossible for small companies) and then prep for the interview at hand. I guess that falls under "motivated enough" :) If you want to be prepared in a general sense, get "How would you move Mount Fuji", a book on those interview puzzlers. The upside of most of those puzzles is that the answer is blindingly obvious once you read it the first time. So read that book, and you're done ;)
