Hire Angular Developers Remotely: Best Questions to Ask

Q 1. What initiated the introduction of client-side frameworks like Angular?

Why ask the question: To comprehend whether the candidate knows the fundamental history of Angular. The ideal answer should be brief while explaining the motive behind the phenomenon adequately.

Answer: In the past, most web developers use jQuery and VanillaJS to develop websites. However, as websites became more prevalent, using the tech to maintain the sites became tedious. Apps with complex functionalities caused the developers severe issues, and jQuery failed to offer features to handle data across views.

This is what led to the advent of client-side frameworks such as Angular. They separate the process’s concerns while dividing the code into smaller pieces of data. This significantly simplified the development process of intricate web apps such as single-page apps.

Q 2. What is the primary intent behind using Angular in an app?

Why ask the question: To ensure the aspirant has a firm grasp of the subject. Thus, a well-prepared candidate will keep their answer concise and to the point.

Answer: Being a comprehensive frontend framework allows Angular to create reliable, modular, testable, and scalable website development. In addition to that,, it also plays the role of a web solution, providing esteemed assistance from development to deployment. Angular is also front-end developers’ first choice as it uses TypeScript, making it easy to scale and avoid minor errors.

Q 3. List some reasons why developers prefer Angular over other Frameworks.

Why ask the question: To see if the applicant is fully aware of Angular’s properties. The benefits can range in numbers, but an experienced candidate will mention the most prevalent ones.

Answer: Angular is preferred by many developers. Here are the reasons why:

  1. Two-way data-binding is possible with Angular.
  2. It is compatible with Angular and static templates.
  3. Angular follows the MVC-pattern architecture.
  4. It proffers numerous handy features like Animation and Event Handlers.
  5. You get assistance for dependency injection.
  6. Adding a customized directive is viable with Angular.

Q 4. Mention the key differences between Angular and AngularJS.

Why ask the question: To see how well prepared the candidate is. Since it is a commonly asked question, the developer’s answer must be quick and precise.

Answer: There are numerous differences between Angular and AngularJS like:

  • Language: When it comes to Angular, TypeScript language is used. It is a JavaScript superset and is statically typed. Contrarily, AngularJS makes use of JavaScript language. Unlike TypeScript, it is a dynamically typed language.
  • Architecture: In the case of AngularJS, Model-View-Controller (MVC) Architecture is used. The Model comprises business logic, the Controller processes the data, and View highlights the data present within the Model. On the other hand, Angular replaces the concept of Controllers with Components. A Component can be defined as a directive with a preset template.
  • Expression Syntax: If you are developing an app with AngularJS, you must remember the correct ng-directive to bind a property or event. While in the case of an Angular app, the property is bound with the “[ ]” attribute, and events are bound with the “( )” attribute.
  • Structure: Maintaining code for large applications is difficult with AngularJS, while it is significantly simpler when it comes to Angular.

Q 5. What are services when it comes to Angular?

Why ask the question: To ensure the aspirant is well-aware regarding the components of the tech. A prepared applicant should be able to articulate a short yet descriptive answer.

Answer: Services can be termed as single unit objects that only get instantiated once throughout the app’s lifetime. Angular services comprise methods that help store the data throughout the app’s lifespan.

The motive behind Angular services is organizing and sharing business models, functions, and logic with different Angular app components. Additionally, the functionalities proffered by services can be invoked from any component like a directive or controller.

Q 6. What do you mean by MVVM Architecture?

Why ask the question: To assess the applicant’s grasp over primary Angular concepts. The ideal candidate must establish the correlation between the three pillars.

Answer: The MVVM Architecture comprises three sections:

  • Model
  • View
  • ViewModel

The model comprises an entity’s structure, meaning it possesses an object’s data. On the other hand, View can be termed as an app’s Visual Layer. It showcases the data contained within the Model, meaning it highlights the component’s HTML template.

When it comes to ViewModel, you can define it as an app’s Abstract Layer. It manages an application’s logic and Model data while displaying it in View. ViewModel and View are interconnected through data-binding, meaning ViewModel takes notes and modifies the apt data within the Model.

Q 7. What is the AOT (Ahead-Of-Time) compilation?

Why ask the question: To know whether the candidate knows the standard Angular terminologies. There should be no beating around the bush for the answer.

Answer: Every Angular app gets compiled internally with the help of the Angular compiler. It takes place within the TypeScript code, where it is compiled and used to produce JavaScript codes. The phenomenon happens only once per user and is called AOT (Ahead-Of-Time) compilation.

Q 8. What do you mean by Dependency Injection?

Why ask the question: Since Dependency Injection is a prevalent app design, it will give you intel on the candidate’s domain knowledge.

Answer: Dependency Injection is one of the most used app design patterns integrated by Angular, forming its core concepts. Dependencies mean services with functionality in the Angular circle.

Such functionalities are needed by different directives and components. Angular facilitates a seamless system where the dependencies are incorporated within the directives and components.

Q 9. What code is used to create a decorator?

Why ask the question: To hire Angular Developers Remotely, it is important to evaluate the candidate’s technical skillset. Therefore, the ideal answer will be directly showing the code to the interviewer.

Answer: To create a decorator called Tummy:

function Tummy(target) {

 tummy.log(‘This decorator is Tummy’, target);


In Conclusion

Hiring remotely and that too for a complex role as an Angular developer is demanding. The angular developer salary is also pretty high. Along with asking these questions you can also team up with Supersourcing to make your hiring process more streamlined.
