U家还是挺不错  遇到面试官人都很好而且strong

非常感谢楼主分享。3个design是面试官随性聊的还是面试之前就说好的？ 感觉Design太大于Coding了

请问下lz能说下当时面这几个design题的思路吗？

The messaging platform system design was a followup because I nailed the coding question. The interviewer asked my thoughts about the system they are currently building. The ads platform system design was a followup from manager round. I guess they were just measuring my experience.
For system designs, I always ask (lots of) questions about what they are looking for. First I'll start with a very simple (naive) design with all major components, and then start to ask the interviewers which component to improve (scale, performance, etc). I like to imagine that we are building a prototype system and then evolve the system as needed.

楼主几年工作经验，要3轮design？
