Many people in software have passed through similarly hard gates in the past.
An engineering degree is harder to attain than a law degree for instance. The question isn't about these gates, it is about the interview practice once one is already through. Do law or medical interviews include questions unrelated to the work that they do in a reasonably analogous manner to leetcode? Maybe they do. Perhaps hiring is broken in all fields.

I didn't. I dropped out of school to work at my first job. That's different from a doctor, nurse, lawyer, CPA or PE who have to meet an industry standard.
