Body:
Hey everyone,
I noticed that a lot of the PDF versions of Alex Xu's System Design Interview Volume 2 floating around online have issues—missing pages, blurry diagrams, or weird formatting.
I managed to find a "fixed" version that is clean, searchable, and has crisp diagrams. I’m uploading it here to the repo for anyone prepping for their system design rounds.
