There was a time when I did assessments for recruitment, I never scrubbed anyone in the The LHS doing the PF part. It held almost zero interest for me. Far more interesting was to assess the person doing the PNF support functions from the RHS, quite a few were scrubbed.
Bluntly, the modern cockpit with its almost failsafe technology has no space for the single pilot ace. Far, far better to have crew members who work together well as a team. How someone performs as PNF or PM is of far greater import.
The unfortunate part of sim assessments is that the assessors who wangle themselves into these positions have egos which don’t match their abilities and worse still, have a poor understanding of what’s important. The hapless candidates suffer.
In my experience, anyone who fancies themselves as an ace almost certainly isn’t.
