The biggest shift in is the tension between the Joint Family System (three generations under one roof) and the Nuclear Family (urban couples living alone).
While many candidates search for "Alex Wu," the actual author of the definitive books on this topic is . Together with Sahn Lam, Xu authored the System Design Interview – An Insider's Guide series (Volume 1 and Volume 2).

In the high-stakes world of software engineering recruitment, the system design interview has evolved into a formidable gatekeeper. Unlike algorithmic challenges, which test discrete coding skills, system design interviews assess a candidate's ability to architect complex, scalable distributed systems. Among the myriad of resources available to aspiring engineers, the materials authored by Alex Wu—most notably within the widely cited "System Design Interview" volumes—have emerged as an industry standard. While often sought after in PDF format for their accessibility and concise structure, the true value of Wu’s work lies not merely in the checklists provided, but in the underlying philosophy of structured communication and trade-off analysis that it instills in the reader.
