Interviewer started with a quick intro and asked about my current project. Coding Question: Implement LRU Cache (Design question). Discussed possible solutions, space-time trade-offs, and used HashMap + Doubly Linked List. Follow-up: Modified the design to handle concurrency (basic discussion). Also asked one array-based problem: Given an array of stock prices, maximize profit with at most two transactions. Ended with 5 minutes of system design discussion (Design a simple URL shortener).
