But why would anybody come work for you then? There are plenty of companies that don't fire, and they would be far more attractive.

The interview process would presumably be shorter and less complain-worthy than the current industry standard.

Well I can confidently say that people I know don't have a problem with the current algorithmic interview process, in fact my friend group generally finds it fun, where as conversely I don't know anybody who would take a job with a non-insignificant chance of being fired.

That's fair, and certainly there are plenty of engineers who are content with the current state of tech interviews, but there also seem to be many who aren't, given that this conversation is taking place on a comments thread full of criticisms of the tech interview process, and these threads seem to manifest at least once or twice a week on HN.
