Hi all, I have an upcoming Amplitude interview that consists of 2 hours back-to-back: * Hour 1: LeetCode-style coding * Hour 2: System Design + “defend your case” For anyone who has interviewed with Amplitude recently (or similar analytics/data-platform companies), I’d appreciate any guidance: * What kinds of system design prompts are typically asked? * What does “defend your case” usually involve — mainly tradeoff discussions, scaling decisions, bottleneck handling, etc.? * How deep do they expect candidates to go (APIs, DB schema, queues/streams, caching, multi-region, monitoring)? * Any recommended prep resources that helped for this style of interview? Would really appreciate any tips or recent experiences (without sharing confidential details). Thanks!
