Regardless of the detail the candidate eventually provided, if she needed two or three probes to describe a specific example, then chances are that the behavior in question is not a recurring part of her life. When you ask “Tell me about a time” questions, don’t judge the response on the quality of its detail. If you do, you will end up evaluating whether the person is articulate or whether the person has a good memory, rather than whether he or she has the particular recurring talent you want. Instead, judge the response on whether it was specific and top of mind.
