I have a company that would like to bring me in to serve me an hour long exam. No resources other than a pencil and paper. I really couldn't get any sort of feedback on the type of exam (implementation or generic) beside that it would test a few specific areas.

Have you done anything like this? What sort of questions did they ask? What's a good way to prepare? I'll probably go in a couple weeks before school starts back up.

A time sensitive exam structure is a weak point for me, so what should I absolutely focus down on?

If they like the exam, that's when I'll get a face-to-face meeting.

An advance thanks goes to everybody who provide their time.
