W: Hi, Larry, are you waiting to see Professor Jamison, too?
M: Yah, since I got one of the five highest grades in her managerial economies 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. Jamison 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 worried 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.
M: That sounds manageable. I guess you can do the work when it fits into your own schedule, too, can’t you?
W: Oh, yeh, you can do the grading in your room or in the library. You just need to get each set back for the next class, but that means you always have at least two days and sometimes four.
M: It sounds great.
W: Good luck with your interview.
Why could the woman give Larry detailed information about the job?
