System design questions have become a standard part of the software engineering interview process. Performance in these interviews reflects upon your ability to work with complex systems and translates into the position and salary the interviewing company offers you. Most engineers struggle with the system design interview (SDI), partly because of their lack of experience in developing large-scale systems and partly because of the unstructured nature of SDIs.
