It’s pretty disappointing when we don’t land the candidate that we were after. There’s a lot of frustration when this happens. In most situations however, there is more than one person in the candidate pool. Someone who fits the need and would be an excellent hire.
On any search you should look at the big picture and and understand that there are some number of potential candidates in existence that would be a great hire. The objective is to make a great hire, improve your business, not to hire one particular person.
