I just become unable to do math during interviews. You know how people hate public speaking, because they feel super nervous, sweat a lot, and have trouble saying what they want? That but with calculous you haven't touched in 12 years.

If they gave me a piece of paper and let me do it without interruption, I could do it, but generally interviewers will sit there and demand you explain what you're doing.
