The interview process for roles involving SQL and Node.js typically starts with a screening call to gauge the candidate's experience and basic understanding of these technologies. Next, a technical interview delves deeper, posing challenges and scenarios that require the candidate to demonstrate their proficiency in both SQL database management and Node.js application development. Questions might include: "How do you optimize SQL queries for performance?" and "Explain how middleware works in a Node.js application."
