This line of reasoning makes no sense at all.

Imagine a math professor would be required to be as fast in answering questions regarding times tables as a child in third class. I bet you wouldn't be able to hire almost any math professors any more because almost all of them would lack this skill!

Nobody would be of course so stupid to judge a math professor by asking them questions about the times table.

Well, but one, and only one, industry is bonkers enough to do exactly this.
