I recently interviewed for a Frontend Developer role at Société Générale.I The first question was: "Why do we use React when plain JavaScript can do the job?" I gave a detailed explanation about how React optimizes the DOM, improves maintainability, and efficiently handles component-based architecture.The discussion stretched for over 20 minutes, yet at the end, the interviewer simply said: "I'm not satisfied with the answer." No explanation. No feedback. No follow-up. Société Générale
