Hi, I have a lot of experience in this area - I'm the co-founder of a program for experienced engineers that brings up their DS&A, SD, behavioral and other gaps to the top tier bar. While people pay a lot of money for our training because they get constant support until they get a job from senior engineers, non technical support , career coaches, mock interviews, etc... almost all of the underlying concepts are available for free/low cost - the problem is actually that there's TOO MUCH information out there and people move through it inefficiently and waste time/energy.
So you'll find thousands of hours of content out there, but two that come up more often then others are useful right now are: 1. NeetCode's video explanations (many are free) and 2. a lot of people like Structy's explanations as well. I would check out both of these as a good starting point!
