Clarify requirements and define constraints (e.g., number of users, data volume).
System design interviews are often considered the most intimidating part of the software engineering hiring process, especially for senior roles. Unlike coding interviews, there is no single right answer, and the scope is vast.
Alex Xu advocates for a structured approach to prevent chaos. Step 1: Understand the problem and establish design scope. Step 2: Propose high-level design and get buy-in. Step 3: Design deep dive. Step 4: Wrap up.
