Needs prep to think of actual experiences you can share that illustrate it. Another question is 'what has gone wrong in one of your past experiences, and why' - really helpful to discuss what you've learnt from past experiences.

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).
