I initially received an online assignment through the company’s portal. It was a system design exercise that required designing a platform where users could play quizzes on their topics of interest with other users in real time. The assignment was well-structured, engaging, and also a good learning experience. In the second round, the same assignment was reviewed by a professional with strong expertise in system design. The discussion was insightful, and the interviewer’s manner of asking questions made the experience even better.
