Process
The interview process involved two coding rounds (LeetCode medium difficulty), one system design round, and then a team match.
For each coding interview, the first ten minutes were dedicated to resume-based questions.
Question 1: Design an LRU cache. Question 2: Provide a bird's-eye view of a binary tree.
I failed the system design round, which focused on designing a rate limiter.
Questions
