Senior Java Full Stack Developer
Summary
🚀 I recently went through a technical interview process with a large IT organization, and it was a good reminder of how frontend interviews are evolving. The discussion wasn’t about syntax or definitions — it centered on how React behaves at scale, how rendering actually works, and how performance decisions impact user experience. ⚙️ There were no “What is React?” or “Define hooks” questions.
