If you asked someone to do FizzBuzz at home and they sent you a git repo with 60+ commits, you wouldn't be a little puzzled about that? That would seem to suggest they really struggled with it.
For a typical whiteboard coding problem, I also wouldn't want to see 60+ commits.
I remember later on I wrote a script that listened to git hooks and rebuilt my project on a remote server. I was still testing manually at that time, as we all do in the beginning, which resulted in a large number of commits so that I could view the results on the server.
I think it's ok to ask "why do you have so many commits?" but not "why do you have so many commits?!?!?!". It's also not ok to ASSUME that a large number of commits is a bad thing automatically, unless you have reasons far better then any submitted in this thread.
