Who is waiting for the man?

W: John, there’s a lady waiting for you in reception. She’s been there for some time now.
M: She’s Amy Grant, the accountant we hired last week. Could you take her over to Human Resources? They can start processing her. I’ll be there in 15 minutes.
W: Sure, I’ll do that. The staff will be thankful for the extra help. Will she start work right away?
M: Yes, but she’ll assist Mary for 15 days first, in order to understand our systems and procedures. After that, she’ll work independently.
