I hear you and essentially don't disagree. But I feel like this might lean a tad toward gaslighting.

• Plenty of people are fine communicators when it comes to genuine collaborative work but still find the "game" of job applications very difficult or impossible.
• Being left alone with a customer is not a thing at all for many roles.
• Embracing diversity in abilities and doing so transparently is a thing that can be valuable for both companies and humanity. Presuming everyone can do all the things is, IMO/IME, damaging. It leads to cutting out people who have something valuable to offer. But also leads to not recognising when people are properly bad at something despite the fact that they really shouldn't be given their seniority and role.

In the end, a job application/interview is not like the job at all (whether necessarily or not). That there are people in the world who would be disproportionately good at the job but bad the application seems to me an empirical fact given the diversity of humanity. And recognising this seems important and valuable in general but especially for those trying to understand their relationship to the system.
