One online assessment round: 1 hour, 2 questions (Easy). One technical interview round: 1 hour, 2 questions (Medium). * Burn a binary tree (BFS) - LeetCode * Alien dictionary (topological sort) - LeetCode / GFG

First, a screening round, then an OA test of 2 hours. You have to solve 2 questions; both questions are on the easy-medium side. Then, a personality test, which was a bit unique. I was rejected after this.

I applied online. The process took 4 weeks. 2 interviews: * Needed to implement min stack at the first one using linked list * Needed to implement LRU cache * Needed to explain about a project I did * Was also asked basic questions about myself
