This post might be a bit heavy but I need to just get this off my chest. I am a former lowly Electrical Engineering major and recently switched to CS and I am a junior now. I have done like 4 full stack web app projects (2 of them are pretty involved and I wrote good readme's for all of em), 470+ leetcode questions (123 easy, 282 medium, 72 hard, mainly did these without looking at the solution at all), team web dev projects for research organizations at my school where I rose as a leader and really drove the projects to completion with planning and my technical expertise, and firmware engineering internship, hackerrank/leetcode and school coding contests this past summer. I go to a US News 50th ranked CS school, but it is not well known so it probably appears even worse to people that don't know the school, 3.9 GPA. Fast forward to now, I only got offers from pretty low tier companies as a junior, which makes me really sad. I got past the OA for some big quant trading firms but ended up eventually getting rejected, because it was clear that I just hopped onto the CS bandwagon last spring and I haven't taken advanced CS classes like Operating Systems, Networks, Compilers, etc.. I am currently debating whether to do a Master's in CS to allow for another internship year, but I spent my entire summer doing things that aren't oriented towards Grad School credentials. I would like advice for how to get into a good grad program and how to participate in conducting research studies and getting my name on papers and shit. Whenever I talk to a professor, they put me on some web app project instead of a real research topic, even though I am pretty comfortable with tensorflow and numpy. I have a learning disability (as you can tell from my english in this post) and so doing well on the GRE is out of the question.
