When I was a hiring manager, I specifically designed an interview process that procured me candidates that were great devs that didn't do well in leetcode style interviews, and as a result was able to hire a much better team than I should have been able to at my budget level. We did this, by doing no-brainer things like, actually reading the resumes.
But good hiring practices are hard to scale. Reading a resume or a person is difficult to teach. But a minimally competent leetcode style interview session can be run with some success by most engineers, so it scales. Which means it worked great for some quickly growing tech companies with large amounts of cash and little need to filter questionable resume lists (usually because their name brands guaranteed high level quality applicants). This then became a fad as every company copied the name brand engineering company without wondering if their hiring process had the same constraints as name-brand co, and is now what the industry thinks is 'the one true way.;
It might be a deciding factor if you get an interview at all, which team you are interviewing with and for which level. Those decisions are made by recruiters, not interviewers or hiring committees.
There are many tricks you can use to get an interview. However nothing abut OPs past shows that he can actually be a productive programmer.
>Dev job at IBM
No details what he did or for how long. I've been in teams with fresh juniors who are amazing. They bring in new knowledge and new perspectives and over all crush the job. Then I've seen juniors who "work" on something for weeks and weeks and when we start for them to demo how far they are we find out that they haven't been able to produce anything working.
>QA at EA
While with normal software I'd say this requires at least scripting skills with games I don't know if that is necessarily true and again probably not a good skill set for getting hired as dev in FAANG
>Cybersecurity team at college
I immediately assume this is some kind of CTF team, which might teach you to use some tools, but again I've seen people in college just "pass through" without really learning anything
If the job OP could do and do well was Amazon help desk then he should aim somewhere between FAANG dev and that position and probably erring on the side of the help desk. The new job will teach them more and in a year or two they can apply for a higher position.
