A、Because his uncle who teaches computers at a university influenced him a lot. B、Because he has the credentials and references

W: Why don’t you begin by telling something about yourself?
M: What would you like to know?
W: The usual, you know, something about your background, experience and anything personal that you feel is important.
M: Well, I was born in a city in the southwest and went to school there, right up through college. My father is a lawyer, and my mother is a doctor.
W: Sounds as if you come from a very professional family.
M: That’s right. One of my uncles teaches computers in a university and has influenced me a lot.
W: What made you decide to come to the east coast and get into the computer business here?
M: Well, after I finished my engineering degree, I began to specialize in computer software technology and I even had my own company for a while. But I think the cities on the east coast are developing more rapidly and offer a more promising future. So I finally decided to leave my hometown, even though it meant tuming down some job offers there.
W: Sounds impressive. Why don’t you have your credentials and references sent to me.’? I’ll show them to the manager. We’ll get back to you in a week.
M: Thank you very much.
