Entretien
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."

My interview process for React and Node.js involves an initial screening where a recruiter verifies my background and skills, followed by a technical assessment to evaluate my proficiency with React and Node.js through coding challenges or take-home assignments. Next, there’s a technical interview with engineers focusing on React concepts, component lifecycles, hooks, and state management, as well as Node.js concepts, asynchronous programming, and API development. Finally, a behavioral interview assesses my fit within the team and company culture, often including questions about past projects and collaboration experiences.
