>The candidate gets 3-6 months of stable employment

To me, "stable" implies I don't even worry about having a full-time job for the next 3-5 years. Anything less isn't stable, unless this would be my second job immediately after the McDonald's burgerflipper one where I was scheduled for random 4 hour shifts seemingly designed to maximize personal inconvenience.

If I knew that my job would only last 6 months, I would have to immediately begin conducting a job search and prepping for it. I put my odds at finding another job before the 6 months is up at less than 60%. Even that number seems naively optimistic now that I've typed it out. Offering me 3-6 months of employment only sounds like a deal if I'm currently unemployed and rent was due yesterday.
