The interview process was generally well-organized and professional, and the hiring manager was polite and respectful. However, I found the technical interview somewhat vague and not well-aligned with senior-level frontend experience. The discussion focused heavily on high-level or theoretical topics such as the Virtual DOM, SSR concepts, and naming commonly used React hooks. While these topics are fundamental, they didn't leave much room to demonstrate real-world senior experience, such as architectural decision-making, performance trade-offs in large applications, debugging complex UI issues, or scaling frontend systems across teams. As a senior frontend engineer, I would have expected deeper discussion around practical challenges, design decisions, and how to reason about trade-offs rather than primarily conceptual questions. Overall, the process was respectful but felt more suited to assessing mid-level knowledge rather than evaluating senior frontend expertise.

What is the Virtual DOM? SSR (Next.js) vs React? What is the most used hook?
