Right, but still nobody is forcing you to continue in a job which it turns out is not a good fit for you. I for my part would consider working on SpaceX rockets a dream job but I know I need at least 16h of downtime every day and a weekend, so that is just not gonna happen.
And even if other company cultures are not as mercifully transparent, IMHO complaining about having to mutilate yourself when you could have just as well simply quit and not mutilate yourself is a bit much.
edit: And I’m not saying a company with this sigma grindset bullshit work culture is perfectly fine. It’s not! That’s why it makes even less sense to me to pour your lifeblood into it when this crap doesn’t suit you.
