Once you've found an A player who's a strong match for the job, bring them on board as soon as possible. Make sure you have an offer ready to go (and that it's a good one, of course). If your hiring procedure is lengthy and drawn out, someone else may be able to hire them before you do. Longer recruiting delays will turn away good prospects, leaving you with less acceptable individuals who aren't as in demand. Overall, it will not help you attract new employees.
