Not that many people actually get fired in a hire fast fire fast workplace. The whole point of hiring this way is allowing yourself to not overprepare in an aversion to hiring poor talent. When you get a poor performer, you just let them go, but the average is not that bad, and you end up filling your billets faster where another company may not at all.

The opposite is 7 interviews and shedding most of your applicants for trivial reasons. Most businesses can't support that, too much work would go undone and they would stop being competitive.

No question the interview process is akin to testing a marathon runner by their 100m dash time.

I was just talking about to implications of poor company chemistry which stems from lack of trust and job insecurity.

I think the best way to evaluate a person is just to talk to them about their experience and why they do what they do. Passion is a critical indicator

Indeed. I remember interviewing for several positions and could have done them with one hand behind my back. A ~year later they were still trying to fill the position but hadn't.
