How to get a “Yes” within 24 hrs of the offer

Regarding extending offers to candidates:

It's critical that you pre-close how much time a candidate has to decide on an offer long before it is extended. The time to do this is during your initial interview with the candidate. It is your job to orchestrate the offer and acceptance for both parties and to set expectations well in advance.

You might say something like this so your candidates:
“At the time that the offer is generated by the company, which is usually after several weeks of conversations, I’m going to ask you to make a decision on that offer within 24 hours. What I’m asking you to do here is to start your decision making at the very beginning of the process, rather than at the very end.

It’s my job to make sure you have all of the information you need and all of your questions answered prior to receiving the offer. However, once you get it, I’m going to ask you to be decisive. Is this workable for you?’
