I once picked up a leaflet from our local university, advertising a taught MA in English literature.
There was at least one basic mistake in the blurb!
I didn’t bother pointing it out, though I dare say more than one other did. I should hope so, anyway.
To me I must say it’s unacceptable for teachers at any level to make basic mistakes, and even more unacceptable for anyone in any sort of teaching-related role to say that these things don’t matter any more, except to nitpicking old pedants (like me ?).
A friend of a dd worked in HR and was frequently faced with a pile of CVs, mostly with similar qualifications and experience.
She said the only way she could weed them down to a manageable number, was by ditching any with basic mistakes.
