How to hire NodeJs developers (10 key questions for a job interview)

Hiring Node.js developers can be a hard task because there are a lot of solutions and frameworks in the market that allow us to write code in the back-end such as Sails, NestJS, Feather or Express. Save some time by asking the developer questions about all those frameworks’ base, like the next 10 key questions for a position as a Node.js developer:

  1. What is the event loop in Node.js?

  2. What are Streams?

  3. What is the purpose of “module.exports”?

  4. How can you configure properties for different environments (production, development, etc.)?

  5. How do you obtain the variables and property values passed through URL (GET method)?

  6. What is a middleware?

  7. What is an EventEmitter?

  8. What is package.json and what is it used for?

  9. When should we not use Node.js?

  10. What is the difference between blocking and nonblocking code?

While the technical questions outlined in the blog are essential for evaluating a Node.js developer's skills, I believe it's equally important to assess their cultural fit within your team and company. Here are a few additional questions to consider:

  1. How do you stay up-to-date with the rapidly evolving Node.js ecosystem?
    This question can reveal a candidate's commitment to continuous learning and their passion for the technology.

  2. Can you describe a challenging Node.js project you've worked on and how you overcame the obstacles?
    This question can provide insights into a candidate's problem-solving abilities and their ability to handle pressure.

  3. How do you approach code reviews and collaboration with other developers?
    This question can help assess a candidate's teamwork skills and their willingness to learn from others.

Remember, hiring Node developer is crucial for the success of your project. Take the time to assess both technical skills and cultural fit to find the perfect candidate for your team.
