I've never answered it wrong and gotten hired for my "thought process" even if I was close. I had to fart around on my own for another ~15 minutes to fix my bugs to make it work. But it seems they just want a guy who memorized it and pretends to discover the perfect solution on the first try.
Whiteboard interviews might miss eccentrics who can't express their clever thoughts verbally or visually, but it can depend on how tuned in the interviewer is to these eccentricities or how much value their team puts on expressive skills.
Algorithm/data structure interviews, whiteboard or not, also have the added benefit of being exceptionally good at eliminating candidates that:
1) Drastically misrepresent their skills
2) Give up easily at difficult tasks
3) Don't seek help from others
4) Frequently have a bad attitude
