W: Good morning, Chuck, are you also here waiting for Professor John?
M: Oh, yes. Good morning, Lori. The professor asked me to come here to have an interview. Do you know something about the job working as a teacher’s assistant?
W: Oh, yes. I know all about it because I have experience in this field. Last year, I myself did it for a long time.
W: Well, actually I think it was the best I have ever had at school. It paid nine dollars an hour, which was three dollars more than the school post office paid us.
M: Yeah, I bet this is a good salary. But what did you do?
W: My responsibility was to help Mr. John grade the students’ homework. It wasn’t hard because the professor was always available if there were any questions. I also can improve myself through doing this job.
M: I think I would enjoy such kind of work. And it would be a very good working experience.
W: Absolutely. You can also learn how to use computer database. That’s a good preparation for lots of jobs.
M: You are right. But I’m worried about how much time it might take.
W: It’s pretty reasonable. Only about five or six hours a week and you can do that in your room.
M: Sounds good. I think I will enjoy this job very much.
W: Good luck with your interview then.
