To be fair I worked pretty hard on the ATPLs and averaged around 93%, when I finally got to an airline interview and proudly handed over my pass results, they only seemed to care that I'd passed them all, the actual % didn't seem relevant at all.
As above though, in a very competitive selection, where you're all on a cadet course, or all bidding for a position, something as small as this could tip the balance. I'm at a smaller turbo prop outfit where it was much more about you as a person than exam results or where you did flight training.
