When You Have to Say No, Say It Quickly
A close contact of mine was hiring for a position in his department at a Fortune 500 firm. He had spent a great deal of time wooing one candidate in particular who initially wasn't sure he wanted to leave his current job or relocate his family but said he might do so for the right opportunity.
After passing several rounds of interviews, it became clear he was the front runner. But the candidate kept asking for more time to make the decision, stalling with more questions, and asking for more in his compensation package, with my contact doing everything he could to accommodate.
