Why did Mr. Green make this call?

M：Hello，this is Michael Green. I applied for a sales representative position two days ago. I am calling to see if the position has been filled.
W：Oh，Mr. Green. In fact，I was just about to call you because you are one of the applicants we’ve selected for an interview. Could you come in this week，sometime between Thursday and Friday?
M：Sure，Friday would work best for me. How about 9?
W：That will be okay. Please remember that there won’t be anyone at the reception desk， so come straight to Room C and ask to speak to Catherine Jackson.
