After having interviewed dozens of people, the idea occurred to me that my ratings for interviewees were a Gaussian curve with a normal distribution. Most people blended into each other - they knew the topics the same amount. Enough to be employed in their current job. Then one in six was a standard deviation below or worse, and one in six was a standard deviation above or better. That might be one reason for the impostor syndrome. Because if we interviewed six people, one would be unqualified, four would be OK but not spectacular, and one would know the subjects better than anyone. So in an interview of six people the best qualified one of the six would have the job. The average four were not truly impostors, but would not get the job unless they had an inside recommendation or if we were really needed someone and there was a shortage of candidates coming in.
