OP, I understand your frustrations. I was there too at one point. I finally had a interview for an internship this summer where the manager was going to test my tech skills. He starts off by saying he doesn't like doing leetcode as they dont test actual understandings. He instead gave me a problem and asked me to solve it in anyway I see fit. I was free to use google or anything I needed. I actually enjoyed the experience as we solved the problem rather than test my memory. For every 10 companies that care about memorizing crap, there is 1 company that will look for the scientist in you and hire you because you are what they need.
