I had to review someone's PR for one interview. Ultimately I failed it because me feedback focussed solely on implementation details and asking if there are better ways to solve the problem (with some suggestions as a nudge). Apparently, that was fantastic and showed all the qualities of good coaching...but they expected me to point out all of the instances of poor indentation and other aesthetic things. My justification that it was unimportant and that running rubocop would fix it wasn't good enough - the PR had to know all of the nitpicks.

You know, if I had to do that for every PR I reviewed, I'd be burned out in no time.

It was a shame, but if I didn't flunk that interview then I wouldn't be where I am now.
