My client was looking for a very social & high energy salesperson.  They wanted someone that would not tire of people & conversations & prospecting.  They thought they found the match.   UNTIL, we used the Predictive Index to identify the blind spots after their behavior based interview!  Turns out, the candidate had very polished soft skills & found it easy to communicate with energy during an interview.  What we uncovered with The Predictive Index was 3 deviations of variance on the extrovert/introvert characteristic.  Sure they could do the job, but at the end of the week they were DONE with people! The risk was “May be drained by heavily social activities”
Would they have made a good sales rep? Perhaps.  BUT - they were at risk of stress & burnout from the highly social job over time.  Their natural & adaptive behaviors where too far apart.  My client realized that they wanted to find someone that would get energized by meeting people, not drained.
