I am recruiting for a direct report with technical skills which are easy to screen, but also someone who people want to work with since our projects are usually done in informal teams. The interviewing team (including me) are introverts, except for 1 guy who is an extrovert and generally a good judge of people. I have been going to the extrovert to ask 'how do you think this guy would be to work with' and have gotten some good insight. But sometimes his assessment really differs from mine (a candidate I saw as mild mannered he saw as being too tightly wound, for example).
Any suggestion on how to weigh "soft skills" assessments from an interview team if they differ from yours, especially if they raise red flags that you didn't pick up?
