I suspect the problem is not primarily one of individual skill. It's one of volume/workload and incentives that don't prioritize fairness to developers.

It's probably exacerbated by the lack of sideloading and alternate app stores on the platform.

Yeah I did some googling and it seemed to indicate the reviewers are actually at Apple... with the scale of work I would expect they were not / be someplace cheaper.

Could sti be hired at Apple directly, but at another city/country with cheap wage costs. No clue though where they have their employees.

What Apple needs is to invest in reviewers that are also good developers who can then spend half their time reviewing apps and the other half developing tools and processes for improving the review process.

I'm no longer engaging with you, because you completely rewrote your comment after I replied to it. That's highly misleading to readers.

The reply below should be flagged and moderated for completely unacceptable behavior.
