I mean, if I ask each of the engineers at a company I'm about to join to do a live coding test, they'll just tell me to go away.
The reason I would ask this because I don't want to join a team that writes bad code.
They would tell me that each engineer did the same test and passed.
I would then say, "I don't believe you, I demand a live exercise so you can't cheat and help each other out". After all, their skills could have deteriorated since they joined!
People are only offended because companies don't believe our past demonstrations of competence.
You get to see their standards when you interview with them. You are free to decline their offer if you feel that the bar was too low, and maybe their engineers write bad code. On the other hand, they do not know the standards of the company you came from.
In 20+ years, I have rarely seen a technical interview actually be indicative of a team’s standards. I’ve seen good, bad, and much in between, but mostly I’ve found the “standards” communicated during the interview to be purely aspirational at best.
