At Google there are two layers of the hiring process. Interviewers provide information for the hiring committee. The hiring committee has the resume. They don't need people to read it to them.

I'm not following. Why would someone read the resume to someone else?

So, when I interview someone, I ask them some technical questions and maybe some questions about their work, and provide structured feedback to a seperate group of people who make final hiring decisions.

There's actually not a whole lot of reason for me to look at their resume. The group who makes hiring decisions has it, so my interpretation of it won't be that valuable. Potentially I could ask them to elaborate on some of their prior work or projects, but that's usually less meaningful than just asking technical questions.

I'm not there to figure out how good the candidate is at the things they claim to be good at. I'm there to figure out how good they are at the things the company wants them to be good at.

(Not trying to claim that I'm actually able to figure out much of anything in a technical interview, but that's the goal.)

Or her/them.

In standard American English, masculine is the default gender when the subject is unknown. So using "him" is proper. Using "them" as a singular pronoun is jarring to the ears.

Third-person singular they has a long tradition in English. It may not be as familiar to you, but it's nothing new.

I was not aware of this, I've mostly heard "they"/"them". I take "he" to be an awareness or assumption of the gender, and find it quite uncomfortable to hear with regards to an industry with such a strong gender imbalance.

No. It's actually a fading usage. The current pronouns when not assuming gender are they/them.
