Having recruited for my team when working in an investment bank, I had no end of highly impressive CV s of super bright over achievers, with fabulous qualifications.

But utterly lacking in common sense and quite often intuitive.

I had a strong liking for mixed teams with people of different backgrounds and experiences. Better environment better results.

Dont know if it works that way on a flight deck but it is short sighted to dismiss people based on a single metric which often has little to do with the job they end up doing.
