I think you're putting too much blame on others rather than the companies themselves. For comp sci, entry level simply doesn't exist anymore. The lowest amount of experience required is about 2 years now. Chances are if you just graduated, there's no real entry level job for you.

The recruiter process is also notoriously bad at any part of the application. I had applications straight up ghosted, responses two years after I applied, responses that they already decided to move with another candidate despite the job listing still open, even a 3 hr interview where I was told I would meet the team (as in personality test), only for it to end up as a 3 hr technical. This was back in 2021 2022, and from what I've heard, it has only gotten worse.
