W: Sit down please, Mr. Johnson.
M: Thank you.
W: I have read your application letter here. You seem to have done very well in school. Can you tell me something about your schoolwork?
M: As you can see, my strongest subjects were art subjects. My best subject was history, and my second best was geography.[23]However, my favorite subject was math, and the results I got in the math paper were quite reasonable.
W: That’s true. Now, can you tell me why you think these subjects will help you in this job?
M: Well, I understand that you manufacture computers, prepare software, and advise customers how to use them. Is that right?
W: Yes.
M: And I’ve been told that working with computers needs a logical mind rather than great skills in mathematics. That’s especially true, I believe, when it comes to writing programs. So I think my results show that I have some ability in logic and in mathematics, as well,
W: So, you would like to write programs for computers, wouldn’t you?
M: Yes.[25]That’s what interests me most about computers, writing programs. And I think the computer industry itself is still expanding enormously. I’m sure that career prospects in the industry would be very good.
W: I see. Well, thank you. I’ve enjoyed our talk. We’ll be writing to you.
M: Thank you. Good-bye.
