While no single book can guarantee a job offer, Ali Aminian’s "Machine Learning System Design Interview" has become an indispensable tool in the modern ML engineer’s toolkit. It successfully demystifies the black box of deploying ML in production, providing a clear, structured path for engineers looking to level up their careers. For anyone struggling to articulate how a Jupyter notebook experiment becomes a production-ready service, this text is essential reading.
