How many staff members are working at the Rosco International?

John: Good morning, Pia Marcotti, isn’t it?
Pia: Yes, good morning.
John: Oh, I’m John Reeves. I manage the sales department here at Rosco International. You can call me John.
Pia: OK, John.
John: Have you already been shown around the company?
Pia: Yes, I got here at 9 a. m. and Suzy gave me a tour of the place.
John: And what did you think?
Pia: It’s a lot bigger than I thought it would be.
John: Yes, a lot of people say that. Now we have fifty people working for us here. Did you bring your CV?
Pia: I sent it by e-mail last week.
John: Oh, yes, of course. I was reading it only yesterday. Now... where is it...ah, here it is, here we are. Pia Marcotti, 26 years old, born in Rome...hmmm...OK, let’s see. Where did you hear about Rosco International?
Pia: My brother worked for you a couple of years ago and has always spoken well of you.
John: Luigi Marcotti, yes, I remember him. How long did he work here?
Pia: I think it was about 10 months. Now he’s living in the UK. He’s been working for a magazine in London for around a year.
John: You’ll say "hi" to him from me, won’t you?
Pia: OK, sure.
John: Now, tell me something about your work experience, Pia.
Pia: Well, I worked in the offices of my mother’s company when I left university.
John: And what sort of company does your mother run?
Pia: It’s a caterers. She does the catering for wedding, graduations, funerals, that kind of thing.
John: And how long did you work there?
Pia: About a year or so. They put me on the phones and I was also responsible for all the advertising and our leaflets, business cards and the website.
John: So you didn’t do any cooking?
Pia: No...they kept me a long way from the kitchen.
John: So what did you do after that?
Pia: Well, I traveled for a little while, mostly in Europe and a little in South America.
John: How long did you go traveling?
Pia: Oh, it wasn’t too long. Maybe about six months. I had a job that was going to start at the end of the year, so I had about six months free, so I thought "why not?"
John: Did you have any problems with the languages where you went?
Pia: Not really. I speak Italian and Spanish quite well...
John: How long have you been studying those languages?
Pia: Well, my father is Italian, so I am fluent in Italian. I have studied Spanish for about seven years, so I can get by pretty well in that too.
