Round 1. Node.js questions on event loop, callbacks, closure, promises, and some other http related questions. Then medium leetcode question - Find longest consecutive string without repeating character. Optimised answer is expected. Round 2 Design twitter. Round 3. Design rate limiter. Result - No contact from them. Interview went really well still haven’t heard from them. All the interviewers were very good, expect the one who took bar raiser. She is arrogant and not open for discussion, for here every problem can be solved by scaling more machines, rather than tackling problem.
