They're actionable advice was:

"getting and applying professional feedback for one's interview skills has a better ROI in my opinion."

And I specifically addressed that: it's difficult to get any actionable interview feedback because companies tend not to supply much (if any) useful interview feedback probably due to legal concerns.

I don't think he was suggesting getting professional feedback from the place that just rejected you.

I think he was suggesting getting feedback from doing mock interviews with friends or interview specialists.

This was my read, also.

Yes, I meant to get professional feedback from a good resource, to help one's interview skills. This can also be extended to improving one's communications skills at work.

For resources of people who might be able to help, I would include people like a mentor, hired professional, or trusted friends who are good communicators.
