Well, here's your problem. You didn't graduate from MIT or Stanford, and you're obviously not grinding leetcode, studying for and taking certification exams, boning up on your brain teasers, or doing mock interviews so you know what to expect, nor are you willing to work for free this early in your career. All of this means you're not really serious about working in the field. Unless you can prove your intelligence and passion, you present a risk to employers. Bad hires are costly.

I'm being heavily sarcastic, but that's just how the game is played now. You have to commit to the full-time job of getting a job, otherwise you will be gatekept out.
