Round 1: Adaptability The first round, with an initial question and follow-ups, assesses your grasp of fundamental concepts. It tests how you adapt and extend a solution as requirements change, revealing your core problem-solving process. Round 2: Deep Dive The second round's lengthy question evaluates your ability to handle complexity and ambiguity. This is where you demonstrate code quality, algorithmic efficiency, and endurance on a significant, multi-part problem from start to finish.
