A Forbes data revealed that the number of Node JS jobs alone has increased by 2500%. As a result, 36.42% of developers today use Node JS framework, libraries and IDEs for app development. Node JS is one of the most popular Javascript frameworks today for building web applications. Apart from being open source and free, other reasons that contribute to its popularity include the convenience of using a single language for both frontend and backend and its ability to handle large amounts of requests. Many popular websites these days like Paypal, Linkedin, Netflix and the like use NodeJS for their websites. So if you are looking to hire Node JS developers for your business, here are some top interview questions to ask so as to hire the right one.
1. What is NodeJS and what is it used for?
This is a basic question to test if the candidate has a basic understanding of NodeJS and its usage. It’s a Javascript run-time environment used primarily for web servers but it can also be used for web applications, RestAPI server and distributed systems.
Q.2. How do you manage packages in Node.JS projects?
There are several package installers with file configuration to manage packages in Node.js effectively. Packages can be leveraged for the use of external modules in Node.JS projects. These packages cover a wide range of functions like data rendering, data validation and more.Therefore, it is important for developers to understand the use of such packages.
Q.3. What is event-driven programming?
Node.JS is built on an event-driven programming paradigm. Anybody who claims to know Node.JS should understand the foundation on which it’s built. The developer should be able to explain in detail along with examples of what event-driven programming is.
Q.4. Walk me through a recent Node JS project you have worked on?
There is no definite answer to it. Here, what you’re trying to know is to get an understanding of the background of the developer, the kind of projects you have worked on. The developer should be able to talk about the kind of projects he has worked on and how he used Node JS. You may, of course, probe a little deeper and ask follow-up questions if needed.
Q.5. How is Ajax different from Node.JS?
The main difference between Ajax and Node.JS is that Ajax is a client-side technology that makes web pages more dynamic and interactive. Whereas, Node.JS is a server-side technology that is responsible for building scalable and high-performing apps. A developer should ideally be able to differentiate between Node.JS and other technologies.
How to hire Node.JS developers for your business?
If you want to build a website using Node JS you need a NodeJS expert in your team who can be responsible for building, maintenance and performance of your web application. However, depending on your project, business goals and budget, you can decide whether to hire a Node.JS developer for full-time, part-time or freelance basis.

Freelance developers – If you simply need help from a Node.JS developer for an ad-hoc requirement and don’t want to invest in a full-time developer, it’s best to hire a freelancer. They are flexible when it comes to mode of payment and the hiring process is also hassle-free.
Outsourcing – If you have a large scale project requirement with tight deadlines but do not want to be bothered with the hassles of hiring developers, outsourcing to a third-party development company is your best bet. They have qualified people onboard and all the necessary tools required for executing the project. All they need is a thorough job description. However it has its downside though. You do not have any control over the output or the process of execution.
Remote hiring – If you want to leverage a full-time developer but the cost of local hires is what scares you, hiring full-time remote developers is your best bet.
