Ok. If the employee said that he will still searching for another job, and my offering isn't the exactly what he wants.. I agree with you! I won't be happy and he neither.
But if he tells me that he have a plan, even if it's to being in another position (like a project manager or engineer for example) and the position that I'm offering could be a great opportunity to him or is part of it's plan.. I would like this employee work with me.. I don't know but.. to me is important to have objectives.. I still thinking about my career plan.
