I've always been in the camp of not doing coding interviews...whiteboard or otherwise. Overall, that's worked well when hiring engineers with 3-4 years of experience or more. Less experienced engineers are very difficult to assess without some kind of coding exercise. All the hires I've made that I'd characterize as mistakes are of junior engineers that I didn't do a coding exercise with and interviewed well, but didn't bring that interview polish to the job. Since instituting whiteboard exercises for junior positions, our success rate has been higher (no pun intended).
