Most everyone with an undergraduate CS degree will have taken an algorithms course. I think the comparisons with designation and examinations is drawing a rough equivalency to these designations, for example. I can't offhand think of another high-skill profession where the interviewing process tends to draw upon one phase of a career (undergraduate studies), and one specific aspect in that phase (algorithms and not say, compiler design, or programming languages survey, or software engineering, etc.), so our field might be a little odd in that respect if indeed that kind of emphasis is rare across high-skill fields. Doctors, PE's, attorneys have continuing education requirements, but I haven't heard of doctors boning up on say, anatomy or OChem for their interviews, for example.

For those who hold a PE, what have interviews in your field been like?
