You're not alone. Although it's never been as bad as not being able to do arithmetic, I can't seem to get a job doing those kinds of interviews. I was close once at Microsoft, after having done 8 hours of coding and linear algebra and other math (that I wasn't expecting) without a slip up, and what I thought was pretty great performance, but alas that wasn't enough either. Most of the time I freeze up and can't think in those situations though, I don't know how I pulled the strength to get through that interview. In the process, due to stress, I developed a huge canker sore in my mouth where there's still a scar. Interviewers dropping hints just makes it worse, it's not that I need hints, it's that I can't THINK when you're sitting there judging my performance, while having to keep explaining my thought process out aloud. Some people are just not built for that.
