Person1: Well , tell me something of yourself .
Person2:What would you like to know , Mr . Green ?
Person1: What working experience have you got ?
Person2:In 2004 , I got a job in the sales department of a trading company near Guangzhou . I started a sales representative . A year later , I was promoted to the position of sales manager . I had that job ever since , which is just over a year now .
Person1: Oh , good . Irene , can you tell me why you plan to quit being a sales manager to work here as my assistant ? Don't you like your present job ?
Person2:Frankly , some part of it I enjoy very much , but I prefer something more professional . It happens that I have a friend working here in this company . She told me the export department was to recruit an assistant . I felt very excited at this news . That's why I'm here .
