[Lewisham]

Where did you get the idea it drives interviewers crazy?

a) I shouldn't ask questions that are in that book, any question found in the wild is banned.

b) I want my candidates to study and show me the best of themselves, and that they want the job and are not wasting my time by throwing their resume on the pile as an afterthought.

c) Cracking the Code Interview is really good at helping you through the algorithmic questions popular on whiteboards. I find the signal:noise ratio on those questions pretty poor, so I ask more straightforward questions that more closely represent things a software engineer encounters in their everyday life. CtCI is good for getting you up to snuff at the stuff you don't do all the time (if ever) just in case you get That Interviewer.

Admittedly, I am but one interviewer and there are many others who do many things many different ways, but I've never heard anyone denounce candidates studying.
