Interview Experience

书接上文https://www.1point3acres.com/bbs/thread-1175978-1-1.html,上轮面试居然给我过了,再次感谢面试官手下留情。

这轮主要是system design + coding。

system design:

设计role based relational database,user, role, permission, resource, 他们的关系应该是什么。太久没用relation db了,完全忘了多对多应该怎么设计,关联表都没写,全靠面试官提醒。

coding:

lowest common ancestor,给了parent指针,没刷到,o(1)不知道怎么做,也是面试官提醒才写出来。

面完一周没消息,应该是没了,也没啥好问的,面的太差。
