I worked at a Chapters (Canadian large chain bookstore, like B&N), and while I was talking to the manager one day he said he had someone coming in for his third interview, and this was for a regular (non-management) position. Someone asked him how many interviews he did with a given candidate, and he said 'As many as I need to do until I'm sure either way'. Perhaps this was just the case with this individual - maybe they just couldn't make a hard decision yet.
