Ask HN: Should I give up on FAANG as a low IQ late 30s engineer?

I am a software engineer in my late 30s and I've been trying unsuccessfully to join faang for a year now. I am unable to pass any type of leetcode challenge. I can barely do leet code easy questions and it takes me ages to get it. I have tried memorising solutions, patterns and grinding problems over and over. I have gone through a few algorithms books (CLRS) but i find the maths and proofs really hard.
