Process
The interviewer was nice, helpful, and friendly. However, I was told by HR that this was a regular technical interview, not a system design one. I had prepped for LeetCode and other technical questions, but that wasn't useful because the bulk of the interview was spent on system design. I didn't do well enough to proceed due to my lack of preparation in that area.
Questions
