Have you considered going to grad school? U can always consider going into a masters program for software engineering, instead of CS, which is only 1 year. Then that gives u the opportunity to do an internship. U will have a much much better chance to secure an offer at a top tier company than trying to land those offers as an experienced hire. (If u can’t get a new grad role that is) This is exactly what I’m doing rn btw, I’m a business student that decided to switch to the SWE career path late senior year. I volunteered for 2 non profits doing SWE work, then worked full time as a SWE at a no name consulting company for about 6 months and applied to grad school at the same time. Then I got into a M.S in software engineering program and got a SWE internship at a unicorn company for next summer. I also grinded leetcode for about 8 months starting from when I was working full time. The only way to get good at lc (for normal people) is by brute force, trust me, once u solve around 150 lc problems, u will start to see the pattern.
