The "Machine Learning System Design Interview" is currently the for ML interview prep. It successfully translates the "grokking" style of backend system design into the ML domain. If you have an upcoming ML system design round, memorizing the 6-step framework alone significantly increases your chances of structuring a passing answer.

Start with a simple baseline model (e.g., Logistic Regression). Only introduce deep learning if the simpler model cannot meet business requirements.
