There is another class of people (in tech industry atleast): Engineers who are rusty and/or who don't interview well.

Tech is so interesting and varied, that my hypothesis is, that there is sizeable chunk of people, who'd switch jobs if interviewing for the next one weren't a big deal. They are solid programmers, with anywhere from 2 to 25 years of experience, but are super rusty in their data-structures, algorithms and system-design skills. They have been at their companies for a few years, have lost touch with interviewing and don't have enough help to get back in shape.

I started out to validate my hypothesis by starting a bootcamp for technical interviewing: http://InterviewKickstart.com. We kick their practice back into gear in a very comprehensive way. It's going better than I'd ever thought I could make of it.

This is a great idea. The technical interview is indeed a skillset (on either side of the table) and it's great to see more efforts focused on educating people to do well with them.
