4 rounds. 1. Programming Round : Working solution for tiny url problem. Assessment based on - Code Quality - Working Solution - Test Casss 2. With a senior guy who asked questions specific to what he had worked on. Web Security and OAuth flow. 3. Data Structure Round 4. Low Level Design Round The lady who interviewed me for 3rd and 4th Round asked very vague questions; I assume she wasn’t sure what she wanted to ask. Asked a question on log management and kept changing the requirements. I was literally at a stage mocking her because of her ambiguous questions.
