Principal Software Engineer Interview Questions

2,162 principal software engineer interview questions shared by candidates

The first round was System design, and as expected it turned out to be API design. But I got unlucky and I got the question which I hadn't prepared (I prepared Tagging system, Color picker, Rate limiter, Youtube view counter, Web crawler, Job scheduler) and I got File System (I thought this question was for System coding round but my bad luck that I got it in System design).
