That would be good. But to be honest, Excel is scripting - in a 2D FRP REPL (something structurally more advanced than most programmers are using day to day). If we're changing hiring requirements to test for bash/Python/Powershell competency, why not actually test for Excel competency?

Maybe that's the problem? Excel is so easy to start with that people with no experience think they've mastered it, and the industry doesn't seem to have specified any best practices, much less testing the interviewees for their knowledge of them.
