W: Hi, Larry, are you waiting to see Professor Gilmore, too?
M: Yah, since I got one of the five highest grades in her class, she asked me if I’d be interested in working as her assistant next semester, I’m here now for my interview.
W: Oh, yes. I know all about that job. I did it two years ago.
M: Really? Did you like it?
W: I think it was the best I’ve had at school. It paid eight dollars an hour, which was three dollars an hour more than I got working at the school post office the year before.
M: That is a good salary. What did you do?
W: I was in charge of grading all the problem sets that were assigned as homework. I never had trouble doing it, and of course, Prof. Gilmore was always available to help me if I had any questions.
M: I think I’d enjoy doing that sort of work. It would be very good experience for anyone thinking about becoming a teacher.
W: Absolutely. You also learn how to use the computer data base, because the records are kept on it. And building up your computer skills is a good preparation for lots of jobs.
M: The job sounds great, but I’m a little worded about how much time it might take.
W: It’s pretty reasonable. It never took me more than five hours a week to do all the grading and then another thirty to forty minutes to record the grades on the computer.
