What did Mike do after his graduation from the university?

W: Is that you, Mike?
M: Yes, ah, you’re Mary.
W: It’s good to see you again. You are an engineer, aren’t you? Did you stay in England after you graduated from university?
M: No, I worked in Canada for two years. It’s a good place except for the terrible weather.
W: That sounds interesting, but I’m sure you are glad to be back. What have you been doing since you came back?
M: I’ve been seeing old friends, visiting my family, buying things for my new flat and just enjoying myself.
W: Haven’t you got another job?
M: Yes, I started a week ago. But what about you?
W: I’ve got a job in a company that sells medical equipment. It may sound rather dull, but I’m a salesman and I really like it.
