Other mistake: When Nick thinks he is going to be promoted he talks to his PAs about moving to the 44th floor. In the shot of the office building (after he leaves the coffee shop on the way to work) it's obvious that the building only has about 10 floors.
Other mistake: Nick finds Darcy working late in her office. He mentions that it is well after 10:00 p.m., but the sky outside Darcy's window is still quite blue. Even if it were the longest days of summer, the night sky in their location would be black by this time.
Answer: She would come in and explain it and they would either cancel it or interview her anyway.
