On your path to hiring dedicated AngularJS developers for your project? We have you covered. From understanding what Angular is and why you would benefit from it to the interview questions you need to ask them, we have listed everything out.
First things first, let’s get familiar with the technology before you interview potential candidates for it.
Introduction: What is Angular?
Angular is a platform for creating front-end interfaces. For single-page applications, it is one of the most popular choices for developers.
Front-end interfaces decide how long your users will stay on your website, interact with your interface, and finish their journey as you have intended them to. This will also determine how many of those users will like to come back to your website.
All of this makes it incredibly important for the developers to create an interactive and user-friendly frontend for the websites. Angular is used by Google, PayPal, Upwork, Microsoft, and many more.
Difference Between Angular and AngularJS
Angular is an umbrella term for all the versions that have been released since the first release in 2010. AngularJS was the initial version. The newer versions include Angular 2, addressing the issues with AngularJS. However, both versions can be used to create dynamic websites.
Benefits of Angular
So, you know why you need Angular for your website, but what does it offer? Here are some benefits of choosing Angular over its competitors.
Readability: TypeScript manipulates JavaScript and makes it easy to follow, thus, Angular offers more readability.
Modules: The codes in Angular are divided into smaller elements called modules. These modules are reusable and make the application more functional since they are divided.
Testing: The above-mentioned modules also make it easy to test and debug the code whenever you want to since they are divided into small chunks.
Maintenance: The simple MVC of Angular results in small, cleaner code that connects the modules. This means better speed and less loading time. The customers will not have to wait for long for your pages to load, and therefore there will be more engagement.
Configuration: Angular uses a default configuration that allows developers to use readymade UI component templates, aiding the speed of the development.
With that, it must be clear why you need Angular for your project, right? Now, It’s better to understand the people you will be screening in the process of hiring dedicated AngularJS developers.
Roles & Responsibilities of Angular Developers
An Angular developer will work on the client side and help build UI services for websites and web apps. They would create modules and components, and after that, they would connect these components to build functional software.
Here, it is important to note that Angular is a framework, and apart from the understanding of Angular, the developer will also need to have other development skills in necessary technologies such as JavaScript. The developers will mostly work in a team and tackle any unexpected bugs.
The job description for an Angular may include (but is not limited to) the following responsibilities.
Building Front-end
Many project managers utilize Angular for Single page development and front-end of websites. A developer’s responsibility here would be to create an interactive front-end for the websites and web apps.
HTML, CSS, and JavaScript
An Angular developer will be writing codes that are clean and can be tested easily. JavaScript, HTML, and CSS knowledge is a must for an Angular Developer.
Building RESTful APIs
Angular comes with its own features and RESTful APIs are one of the most important ones. The knowledge of building RESTful APIs for single-page applications.
Unit Testing
After each development phase, Angular developers will have to perform unit testing. The testing includes code units, complex testing, testing of services and components, and so on.
Access External Data Sources
The developer should have the operating skills to access external data sources and APIs to extract the data required from third parties.
Bug Fixing
The bugs should be fixed as soon as possible by the Angular developers. Sometimes they may even have to fix bugs in other’s codes.
Therefore, it becomes essential for them to know how to read a code that is written by someone else.
Drive to Learn
Technologies like Angular constantly keep updating, with new versions released each year. Angular developers thus should always be ready and strive to learn new technologies to stay up to date.
Now that you know about the roles and responsibilities, to filter out the resumes, you need to know what skills you require from your hiring based on your project requirements.

- Building and testing the test scripts and configurations for continuous integration environments.
Now, time for the skills that are not necessary but good to have for Angular developers.
- Solid knowledge of TypeScript features like decorators, generic types, enums, unions, etc.
- Understanding REST architecture
