Here is what I'd recommend - buy a copy of cracking the code interview (its maybe 20-30$), and do every single problem (or most of them) in there by hand on paper. Then reach out to some software devs you know and have them give you mock interviews (if you reach out to me I'd be more then willing to help). Then you will be prepared to ace any big tech co interview. Apply to as many of these jobs as you can (I applied to over 100 and got a job at one of the FAANG). Or if that's not working, you could try something like TripleByte to get in the door
