It makes complete sense for your first job and when you're unemployed, but as someone with a couple jobs under his belt already, I have no interest in interview prep anymore unless it's relevant to my work and there's a clear ROI.
The way I see it, no experienced candidate should have to do "interview prep" because the work that he/she does on the job should be more relevant to his/her ability to do the job than any form of interview prep.
To make an extreme example, John Carmack's work time is probably better allocated actually doing work than brushing up on "Cracking the Coding Interview" problems. In an ideal world a software engineer's candidacy for a job would be based strictly on his ability to do the job, not academic trivia questions.
This got me thinking. Since John Carmack is a person we can probably all agree is a talented programmer and all round smart guy ... I'm curious how he would fare if he was handed a standard set of Google/FB interview questions
