@freemo Hiring somebody is like dating, you don’t want someone who’ll bring eggshells and personal baggage to the table
but using thry them singular is standard english going back hundreds of years. So it woukdnt strike me as unusual.
I think I'd be suspicious of someone referring to themselves in the third person on their resume no matter what their pronouns were.
If they list their pronouns as a line item near their name, I think some hiring managers might be more likely to include or exclude for that reason alone depending on the politics of the hiring manager, irrespective of the pronouns that are listed.
