I hope you're stance assumes you know why the candidate reversed. If you don't know for a fact that it was a cynical or frivolous ploy, then it can't have much

I hope you're stance assumes you know why the candidate reversed. If you don't know for a fact that it was a cynical or frivolous ploy, then it can't have much bearing on their reputation. Perhaps they accepted the offer, closed their search, and something came up. Perhaps a bad thing, such as cancer or rehab or mental care, or a neutral thing like their military spouse was transferred.
