How to Interview and Hire JavaScript Developers

JavaScript emerged on the scene more than 2 decades ago, and it remains one of the most popular languages even today. This open-source language many advantages, which are as follows:

  • This dynamically-typed language provides plenty of flexibility.
  • It makes web development easy.
  • JavaScript integrates seamlessly with HTML and CSS, which makes website development easier.
  • Programmers can use excellent open-source libraries like jQuery, React, etc. when they work with JavaScript.
  • The rich ecosystem of JavaScript offers many advantages. For example, Node.js, the popular runtime environment is based on JavaScript.
  • JavaScript programmers don’t need to spend time on setting up an environment for JavaScript development. All modern web browsers like Google Chrome, Mozilla Firefox, Safari, etc. support JavaScript.
  • Coders can use many popular JavaScript-based frameworks like Vue.js, Express.js, Ember.js, AngularJS, etc., which makes development easy.
  • Not just web applications, but you can use JavaScript-based libraries like React for developing mobile applications too.
  • JavaScript works very well with MongoDB, the popular NoSQL database.
  • It also works well with Ajax, which makes it easier to develop web applications that don’t interfere with the display of existing web pages.
  • JavaScript helps to create performant and scalable web applications and websites.

This isn’t an exhaustive list of the advantages of JavaScript, but you get the point! You can see why JavaScript has such high demands and why full-stack developers with JavaScript skills get such high salaries in the United States!

Hiring JavaScript experts can be hard! You need to choose between part-time freelancers and full-time dedicated JavaScript developers, therefore, you need to choose the appropriate hiring platform.

You need to interview them. Look for the following skills in a JavaScript developer:

1. JavaScript development skills

JavaScript programmers should have the following primary technical skills:

  • JavaScript including its strengths and limitations;
  • HTML5 and CSS3;
  • JavaScript frameworks and libraries like AngularJS, jQuery, Express.js, Ember.js, ReactJS, React Native, Vue.js, etc.;
  • Node.js;
  • Relational databases like MySQL, PostgreSQL, etc.;
  • NoSQL databases like MongoDB;
  • Ajax.

They also need a thorough knowledge of the following:

  • Asynchronous programming;
  • Web design;
  • Best practices to deliver a great user experience;
  • How to use JavaScript to develop scalable and performant web applications;
  • How to use frameworks like React Native to develop near-native mobile applications.

2. Other app development skills that to JavaScript developers need

Look for the following additional technical skills when you hire JavaScript developers:

A. Other programming language skills

JavaScript is a powerful language, however, effective developers need a thorough knowledge of one or more key languages. Take the example of PHP. It’s a very good scripting language for server-side scripting, whereas JavaScript is excellent for client-side scripting.

Many software development projects involving JavaScript have more complexity than simple e-Commerce development. A JS developer that knows the strengths of PHP along with JavaScript can contribute far more to such projects.

Even for simple projects like WordPress development, you might have customized requirements. For example, you might need to add JavaScript code in WordPress pages. Having a good knowledge of PHP can help here.

B. API development skills

Developing your own 1st party APIs can help since APIs provide a consistent framework for the front-end of your application to access the back-end. Look for a web developer with JavaScript skills that knows how to develop RESTful APIs since REST (Representational State Transfer) is the de-facto standard for API development.

Hire JavaScript developers that know the following:

  • How to use API development and documentation tools;
  • How to host APIs using on a cloud platform;
  • Using modern databases like PostgreSQL and MongoDB to develop the back-end;
  • How to secure APIs using techniques like authentication token, encryption, quotas, throttling, etc.;
  • How to create effective rules for API requests and responses.

C. In-depth knowledge of cloud platforms

You will likely use a cloud platform for your app development project. Managed cloud services providers like AWS or Microsoft Azure handle the infrastructure provisioning and management, which saves time for you.

The type of cloud platform you use depends on your software development project. For example, if you are developing web applications, then a “Platform-as-a-Service” (PaaS) platform will help.

PaaS platforms manage cloud infrastructure, networking, storage, operating system, runtime environments, etc. This enables you to focus on development. Reputed PaaS platforms have robust DevOps tools and auto-scaling solutions. Look for JavaScript programmers that are familiar with popular PaaS platforms like AWS Elastic Beanstalk, Heroku, etc.

On the other hand, using a “Mobile-Backend-as-a-Service” (MBaaS) platform if you are developing mobile applications. MBaaS platforms manage the infrastructure, persistent storage, etc., therefore, you don’t have to spend a high amount of time on mobile backend development. Hire JavaScript developers that know popular MBaaS platforms like AWS Amplify.

D. The understanding of the strengths and limitations of the JavaScript ecosystem

JavaScript has a very rich ecosystem! You can achieve a lot if you know the strengths of this ecosystem. At the same time, there are a few limitations of JavaScript and its ecosystem. JavaScript experts should know them so that they can use appropriate workarounds.

An example of the strengths of this ecosystem is the rich collection of open-source tools and frameworks for Node.js. Whether you are developing an e-commerce site or a more complex app, the open-source Node.js tools and frameworks can expedite your project.

Let’s consider an example of a limitation. Take React Native for example. This JavaScript-based framework can help you to build near-native mobile applications.

You can run a React Native app on both Android and iOS with a very high degree of code reuse. This keeps your development and maintenance costs under control.

React Native can deliver a far more near-native user experience than other hybrid frameworks like Apache Cordova or Ionic. However, it falls short of native user experience since native apps can seamlessly use device-specific hardware features.

While this is a limitation, JavaScript developers with years of experience know how to work around this. By using native modules along with React Native, they can overcome this limitation.

Hire JavaScript developers that know the strengths and limitations of this vibrant ecosystem. This improves the chances of success of your project.

E. Application security knowledge

JavaScript is a dynamically-typed language. While this gives it a lot of flexibility, there are chances of variable type-related errors that are hard to debug. This can give rise vulnerabilities in the program and hackers are experts in exploiting vulnerabilities in the code! You need JavaScript experts that know how to code secure applications.

They need to know the following:

  • How to proactively identify key application security risks like injection, broken authentication, etc.;
  • How to use tools and techniques like multi-factor authentication (MFA), encryption, etc. to secure applications;
  • The importance of including application security and compliance testing in the CI/CD pipeline proactively instead of treating them as the last task in the project.

F. The knowledge of succeeding in software development projects

A JavaScript developer needs the following skills and competencies to succeed in a software development project:

  • Knowledge of “Model-View-Controller” (MVC) and other popular design patterns;
  • Code review experience;
  • The ability to work with web design practitioners so that the code reflects the user interface design principles;
  • The ability to collaborate with testers and DevOps engineers;
  • Familiarity with GitHub, popular DevOps tools, and other modern development tools.

3. How to hire the best JavaScript developers?

Now that you have the clarity on the skills required, you should take the following steps:

1. Decide whether to hire JavaScript developers from websites providing freelancers or a JavaScript development company

You need to decide carefully about the hiring platform you choose. If you hire the right people, then your chances of success increase. On the other hand, hiring incompetent people can create serious deviations from your budget, schedule, and quality objectives. Turning troubled projects around can be hard, therefore, prevent your project from becoming a troubled one!

You can hire JavaScript developers from freelancer platforms. General-purpose freelancer sites can help you to get a part-time developer at a low rate. Freelancer platforms that focus on software development claim to have stringent screening processes, therefore, you can find high-quality developers there.

These freelancer platforms don’t provide any project management support though. You are left to manage part-time freelancers that might work on multiple projects simultaneously. These platforms deduct up to 20% of the earnings of the freelancers, which can demotivate many freelancers. They may leave your project, which exposes you to more risks.

For complex projects, hiring dedicated JavaScript developers makes more sense. A software development company will be a better bet for you in this case since such companies provide full-time developers. They can provide replacement if the original developer leaves the project.

Software development companies appreciate that you might be using sensitive corporate information as part of your project. They implement physical, technical, and procedural safeguards to protect your sensitive data. This is another key advantage. Analyze your project requirements carefully and choose a hiring platform.

2. Interview the candidates to find top JavaScript developers

Now that you chose a hiring platform, you need to interview the candidates. If you know JavaScript well, then you can interview. Alternatively, ask for help from a knowledgeable associate or get interview questions from the Internet.

Remember to cover all the technical skill areas that we have highlighted. Focus on project experience and not just testimonials. Ask the candidates about the complex projects that they have worked on. Find out how they managed to deal with the complexities.

Explain your project requirements and ask how they would approach them. Look for specific recommendations and not just high-level statements.

3. Provide relevant details about your JavaScript development project

You need to provide the required details of your application development project for the new software developer to be successful. Provide business requirements, technical solution documents, test plans, etc. You need to introduce the new developer to your larger team and explain his/her responsibilities.

Describe the technical environment of your project and provide the required access to the new developers. Show your code repository on GitHub or other tools that you use. Explain your project schedule and key milestones. Describe how you review and approve milestones. Explain the payment T&Cs to the new developer.
