For what it's worth, I didn't have to whiteboard once during my several interviews. If you're interviewing with new SF or NYC startups, you'll find many of them care far more about practical* skills than pop quizzes. This certainly isn't universal, but it shouldn't frighten you away from trying interviews.

I need to take time to build code I can actually show off.
The things I build now are essentially web interfaces sitting on databases. The problem is they aren't exactly.. or at all.. legal.
Great learning projects (putting my home video library into a web interface, with episode data from a TV series API) but not something I feel I can show.
