Absolutely savage way to make a very good point. (with a colloquial implied "It" of course)
While your response is clever, I am not writing a communication piece for a large bank.
> I'm not sure how you can determine the background of someone by how fluently they can write a language - particularly when the piece in question is written better than what most college students in the US can produce.
Perhaps not so much grammatically, but the text intonation and others parts of the text do not give the proper formal tone of the comm.
> when the piece in question is written better than what most college students in the US can produce.
As if this piece of information is some high bar to overcome.
> Still surprising to see a poorly written piece of text.
What's the subject of this sentence fragment? Are you relying on a colloquial implied "It" (as in "It's still...") or perhaps you are talking about your own surprise, e.g. "I still find it surprising..."?
> Nubank's comm leadership
Is this some slang for PR department? Or maybe Communications Team leadership?
> would have an extensive language background in English
I'm sorry, I don't follow at all. Hazarding a guess by rearranging the words a bit - do you mean: "would have an extensive background in the English language"?
I'm not sure how you can determine the background of someone by how fluently they can write a language - particularly when the piece in question is written better than what most college students in the US can produce.
