Ironically I think this attitude is what encourages the bait-and-switch scenario. If someone tells you before interviews they want to work 4 days, 100% chance they'll be rejected. But if a perfect candidate gets to the final stage and then tells you they will only work 4 days the odds are much better and the leverage is on their side. Also there isn't really part time / full time with salaried work. I doubt you're paying overtime if someone stays in the office for over 40 hours. Hiring for presence over productivity doesn't seem like a good metric.
