"The last time I went through a massive, all day technical interview, I didn't get the job, partly because I didn't review my data structures and algorithms book (again)" Which means you're not using that stuff on a daily basis. Which is fine. You're probably doing other things. Development is more than just data structures and algorithms. Yet, that's all many interviewers want to ask about. Here's my guess: you probably reviewed that stuff prior to job 1. You got that job, due to short term memory, then you went to work. Now you want to go to job 2 (or 3 or 4). And you find yourself having to "review" material that doesn't stick to short term memory, but I'm sure you know damn well how to find it and interpret it if you needed to. No doubt at all.
