Just took an exam in UIUC's CS473 yesterday (http://www.cs.uiuc.edu/class/sp12/cs473) -- the two cited references are Jeff Erikson's notes as well as the Berkeley textbook (we refer to it as "the Dasgupta book"). I personally found the Dasgupta book an easier read / good introduction before reading Erikson's notes. Both were invaluable studies and in retrospect all interview questions basically test this information, for those either not in university or wanting to learn to ace those big-O rundowns.

If I wasn't in / wasn't able to attend / dropped out of college, I'd just sit and read all of these notes and I'd probably be okay.
