Zero Dark Thirty is a single place for interview preparation, well atleast a single place to have all links and documents for preparation. It will have solutions from different places for DSA, generic DSA problems and theory, notes in PDF for reference, LLD, HLD materials related to PDF, probably some LLD projects and HLD designs, CS basics notes.
As Kathyrn Bigelow explains, "it's a military term for early morning before dawn, and it refers also to the darkness and secrecy that cloaked the entire decade-long mission."
NOTE: This project is educational and preparation for interview for product companies, solutions might be best, but imho computer science is opinions...So take everything here with a pinch of salt.
