What are some good resources to learn data structures and algorthms for FAANG interviews?

Hi all,

I would like to prepare myself for interviews at FAANG. In the process, I would like to learn data structures and algorithms to a solid level. What are some good resources? books, video courses, etc?

side note: I have been a JavaScript Developer for 4 years and do some python. I never had to do any serious algorithms so far.
