While it is easy to get a developer, getting the right full-stack Node.js developer with the right skills and experience in full-stack development is difficult since most companies are competing to get the best remote full-stack Node.js engineers.

We are here to assist all employers who wish to hire a Node.js developer on their own. Self-hiring a developer takes quite an experience in software development. But if you are a non-technical manager looking to learn how to hire the right developer and what questions to ask before you hire the person, then we have prepared a great resource for you.

​​Skills to look for when you hire a Node.js developer

1. OOP awareness

OOP makes it easy for developers to learn other programming languages. Also, most developers initially become front-end developers, but as experience increases, they become full-stack developers.

Thus, it is evident that full-stack experienced developers must be aware of the basics of OOP. When you need to develop an e-commerce web or mobile application, you should work with a remote full-stack Node.js developer who is well aware of the OOP paradigm.

2. Third-party integration capability

You would want the best full-stack Node.js developers who know third-party integration, such as Amazon services, MailChimp, etc, which are quite standard nowadays in most sites and applications.

So, hire developers who know about these third-party services and take the utmost advantage of them. This is the kind of stuff such as using Node.js to make apps for Shopify, incorporating live social feeds on your website, etc.

3. Database skills

Knowledge of the database may be considered an important prerequisite for recruiting fantastic full-stack Node.js developers. Most full-stack Node.js applications and other novel applications are normally based on databases to store and retrieve data.

Developers have to know how a database works (and the query language used in manipulating it) since it is priceless in making one move up the ladder of full-stack development.

4. Knowledge of front-end technologies

Front-end technologies enable a developer to create user-friendly usability for web applications. No one wishes to hire a full-stack Node.js developer who is not well-versed in the latest front-end website planning and development tools.

Instead, companies need to hire a Node.js developer who is entirely aware of the latest tools and techniques for building appealing user experiences. Skills in jQuery, ReactJS, LESS, HTML5, and Angular make these versatile for nearly any project.

5. Exposure to Git, SVN, Mercurial

Software development is a part of knowledge about code version control tools. There are numerous code version control tools, including Git, SVN, and Mercurial.

In addition, that might be helpful in the coding activities to be accomplished by the developers in tracking all the changes. Developers with good knowledge of such platforms can efficiently work on any project.

6. Skill with JavaScript and its frameworks

Reasonably, good skills in JavaScript would be more than any other script. JavaScript has numerous frameworks, including Angular, React, and Node. Most sophisticated programmers use all of these and enjoy the different features each has in store.

Remember that the full process of full-stack development is a separate activity, and one needs to know all the different frameworks. Therefore, ensure to hire a Node.js developer who are well familiar with JavaScript.

Top interview questions to hire a Node.js developer

What is a buffer class in Node.js?

The Buffer class stores raw data like an array of integers but it corresponds to a raw memory allocation outside the V8 heap. Buffer class is used because pure JavaScript is not compatible with binary data.

What is Event Loop in Node.js?

Node.js implements event loops for asynchronous callbacks. It is the basis of the non-blocking input/output in Node.js, thus being one of the most significant environmental features.

Why is Node.js single-threaded?

Since Node.js is using a Single-based model along with a mechanism of JavaScript callback, Node.js is also single-threaded in nature. Node.js is single-threaded as it tries to simplify the implementation of the code and would ensure better performance along with scalability for the web loads normally. If the developer is aware of this, then you can interpret that they know all about network calls, file system tasks, DNS lookup, etc.

State the difference between process.nextTick() and setImmediate().

Difference between method and product. It is done by using nextTick() and setImmediate(). Next Tick() delays the execution of action until the next go around the event loop or calls a callback function after the complete execution of the event loop, whereas setImmediate() executes the given callback on the next cycle of the event loop and lets the control revert to the event loop for any I/O operations.

Distinguish between readFile and createReadStream.

While explaining the difference between readFile and createReadStream, the developer would be able to prove his/her coding ability, as well as file implementation. In this case, the response would appear to be: readFile loads the entire file into the mentioned memory. The createReadStream reads the entire file in batches of predefined lengths.

Hire a Node.js developer, Work Model

When you choose to work with the developer also referred to as the "work model," it will determine how well your project will turn out. This section shall explore the different work models available, from freelancers and agencies to full-time hires, and how each will affect the cost, dynamics of your team, and control over your project.

Work Model: Defines the structure of your engagement with the team of the service provider. Here are some common models:

1. Fixed-Cost Project

In a fixed-cost project, the agreed-upon total cost for the project is established at the beginning and will remain constant throughout the development process regardless of any changes or adjustments.

As such, fixed-cost projects are very dependent on clarity in requirements. Such projects suit well-defined projects with stated features and functionalities, especially those that have predictability in terms of cost and clear-cut milestones. However, elasticity for change mid-development may be required from the rigidity of the approach.

2. Time and Material (T&M)

The T&M model is a kind of remuneration in which clients pay for the actual hours worked and materials used by the development team. It is flexible enough for projects that are gaining requirements in the process, but close monitoring is required if you want to manage your costs well.

This can be good for projects that have dynamic needs or for long-term maintenance where you can easily change. It's good for projects that require a lot of time to accomplish a certain objective and need quite simplistic resource allocation. Cost estimates vary with the number of hours allocated to a project, therefore one needs careful management.

3. Dedicated Team

A dedicated Team is a team where you hire a Node.js developer who works on your project alone. As they work with you on your task, you get to experience continuity of the working experience along with an in-depth knowledge of the requirements of your project.

This model is suitable for larger projects where you require continuous development and highly customized services.

While it boasts the benefits of focusing team efforts and shorter cycles of development, it is relatively more expensive than any other model. Conversely, the project-based model of development is much more apt for specific projects that would prefer short-term results and clear deliverables.

4. Project-Based Development

Project-based development includes the actual details of tasks like building a payment gateway or creating a microservice. It is well suited for those projects that are defined with a short-term scope, with a defined deliverable. It saves costs on some specific issues and saves time in turnaround.

However, some lack of engagement for ongoing development needs is not without its drawbacks. The best work model depends on your project scope, budget, and flexibility needs. For straightforward, fixed-scope projects, consider a Fixed-Cost Project.

Final Words

Finding Node.js talent is something of much need, and hence, screening for the right talent does pose its problems, be it ranging from understanding different levels of skills to exploring various options for hiring.
