There is some creativity in the rest of the CV, between what kind of experiences are included and how they are described. But that would be far harder to generate fairly.

In think choosing the summary is a fair design choice since it prevents the LLM from just... making up a perfect candidate.

"I'm a fullstack professor of software design with 90 years of experience expecting a junior internship position"

I assume they meant they can't come up with a reasonable justification.

> They state that unlike the rest of the resume, which is largely factual

largely factual? A resume is usually more than a bunch of dates and titles of positions.
