It's a buyer's market - he should spend the hour with an LLM iterating on his resume.

Perhaps it is easier to understand once you acknowledge hiring managers don't handle a hand full of applications at a time but hundreds, and half of them are dropped right at the first round. What compels you to spend your time pulling this candidate into an interview round over anyone else? The candidate clearly didn't even bothered with a spell check.

Half of the issues pointed out are more than stylistic (activity instead of impact, generic/no prioritization). Even without stylistic issues it's not a compelling resume.

And basic spelling mistakes are more than a stylistic issue, it shows a real carelessness that it's hard to imagine wouldn't be in their work
