When I was interviewing candidates in the 90's and 00's, I did the whiteboard thing, but not to implement strtoul (my Microsoft interview) or some algorithmic thing. I'd pick out a recent problem that was solved in our actual code base, clean out anything proprietary, and distill it down to something that could be designed and coded in about 40 minutes or so. That way, I could cover domain knowledge and coding knowledge in a microcosm of what the interviewee would actually be doing day-to-day.

If I were doing it all over again today, I'd skip the whiteboard and bring along a laptop loaded with our compilers and toolchain and any supporting libraries needed to solve the problem. I'd mirror it to the screen in the interview room so we could discuss the solution as we went.
