Honestly, this is the most toxic thing about job interviews for me - "hey can we do the thing where you pretend you didn't have a string of shitty jobs for 5 years? because obviously you were at fault if they were shitty." Most jobs are pretty shitty, the idea that you need to demonstrate toxic positivity about how shitty it was is just so inauthentic.
Another way to think about it, are you able to tolerate the less than perfect aspect of a job while still being pleasant to coworkers. A lot of people can’t, and a lot of companies try to avoid those people.
In my experience most companies work with a wide distribution of people. This "we avoid hiring people who have defects" reads as disconnected from reality. Nobody is perfect, and most companies are average and have average people.
