My interview gone through SQL and Next.js, the process usually starts with a basic screening to assess the candidate's foundational knowledge in SQL queries and Next.js frameworks. This could include questions on SQL data manipulation and querying techniques, such as "How do you optimize SQL queries?" or "Explain the difference between INNER JOIN and OUTER JOIN." For Next.js, questions might focus on its features and use cases, like "How does server-side rendering work in Next.js?" or "Can you explain how to implement static generation in a Next.js application?" The interview could progress to more practical tasks, such as writing a query to solve a specific problem or developing a small application or component in Next.js to demonstrate the candidate's coding abilities and understanding of React-based frameworks.
