Telling this first is a good way to have every company think that 5 days/week is an organizational requirement and brush off the candidate. Having the candidate wait until after the interview puts them in a much stronger negotiating position, namely it forces the company to assess whether or not 5 days a week is a legitimate requirement or not. Many parts of the interview process are unfair to candidates, such as not advertising salary ranges in advance, forcing candidates to take vacation time to attend interviews, etc. This is merely a way to balance the scales away from the company, which generally holds almost all of the power in a negotiation, especially at the start, before an offer is made.
