At many bay area startups I've worked for we would do whiteboarding sessions but I would stress that the candidate "treat me like google". I would actively encourage them to ask questions of the type they'd look up, to be comfortable being collaborative. This to me showed much more about a candidate's ability to work on a team, learn quickly, and apply what they've learned than any whiteboard session entirely from memory could prove. This becomes even more important the further out of school a candidate is; some of us took algorithm classes decades ago.
