Huge management red flag for a bunch of reasons. It means people will start to tell their bosses what they want to hear. Instead of products you'll build a fractal of potemkin villages.
That's hardly helpful advice. You don't have recruiters telling job applicants that they do not tolerate mistakes. By definition, employees get no warning before being fired for making a mistake, which is hardly the situation for advice such as "you don't want to work there anyway". When that happens, all there is to do is gather all your stuff, rethink your life, and update your resume, and prepare to explain in the next job interview how your last job finished so abruptly. Neither of these steps is in your best interest.
It matters nothing if anyone claims that making mistakes is human nature. What it really matters is whether your organization employs people who weaponize mistakes. Another fact of human nature is personal ambition, and there are far too many people who don't mind throwing others under the bus to use them as stepping stones in their career paths. Some of those types succeed, others try until they succeed. What's your answer for that?
The interview is not just where they figure out whether they want to hire you, but where you decide whether or not to accept their offer.
You are allowed to interview the interviewers. In fact, you'd be a fool not to, since this sends a positive signal that you are interested but not desperate. Makes you seem like a quality hire.
