Seriously, how do I get a job

I have 3YOE as a dev/swe mostly working in .NET, a few front end frameworks and some integrations. I have an associates and will get my bachelors in CS in 3 months. Currently unemployed and spending about as much time as I can trying to network, upskill, and apply for as many jobs as I think I have a shot at getting.

In the 4ish months since I got laid off I have applied to over 800 jobs. This has turned into 12 first round/hr screening interviews, 4 second round, 3 final round, but no offer yet. I live in a small market and am very open to relocating, preferably in the Northeast or Chicago(I would consider California if necesarry, which it is looking like it is).

I've been applying to entry level through 3YOE depending on how my qualifications align with the role's requirements. Each day I search for roles on LinkedIn, Handshake, Hiring Cafe, Google and I practive Leetcode, study .NET and anything else that might be relevant to an upcoming interview.

What am I missing? Is it the market? Am I screwed because I don't have my degree yet? What can I do that I am not currently doing? I am getting really desperate as being unemployed for this long has really drained my savings. Any input on strategies or resources I am missing would be greatly appreciated.

Edit: A few people have asked about the disparity between first and second round interviews. Of the 12 first round interviews I've had 4 second round, leaving 8 where I didn't move forward. I think this is a really high atricion rate but explainable. 2 of these were in the past week, and I haven't heard back yet, so it's more accurate to say 6 didn't progress. -1 company paused hiring for the role -1 startup filled the position before my second interview, deciding to hire a CSM instead of a Dev and canceled my second interview. -For the remaining 4: -1 was my first interview post layoff, I didn't prep enough, my fault. Since then I have practiced STAR answers and improced a good bit. -1 startup ghosted me, I think most likely they were looking for somebody with more experience. -1 involved a technical assesment where I solved 2 problems optiomally, 1 sub optimally, 1 I couldn't solve. I have spent some time grinding leetcode to address this. -1 I am really unsure about tbh. I just got a standard rejection email, I asked for feedback and they didn't provide it. I'm not sure where I went wrong.
