To hire a NodeJS developer, a CTO or IT recruiter can ask questions about the entire frameworks’ base, which is Node.js itself. If you want to hire a Node developer, you can consider the following questions:
- What is the event loop in Node.js?
- What is the purpose of “module.exports”?
- What are Streams?
- How can you configure properties for different environments (production, development, etc.)?
- How do you obtain the variables and property values passed through URL (GET method)?
- What is an EventEmitter?
- What is a middleware?
- What is package.json and what is it used for?
- What is the difference between blocking and nonblocking code?
- When should we not use Node.js?
Given these questions, the CTO or vendor will look for the skills of NodeJs developers and support their recruitment process.
