Hey everyone, I'm a 2nd year CS student at top-4 IITs heavily targeting quant trader/systems/SDE role specifically aiming for top-tier HFTs. I have a strong competitive programming background and am comfortable with standard data structures and algorithms, but I know these firms place an incredibly high premium on deep, low-level C++ systems knowledge in their rounds.
For those who have cleared these interviews: What are the absolute best technical books, references, or advanced topics I should focus on to bridge the gap between CP code and production-level standard mechanics?
Appreciate any guidance. Thanks!
