How To Find AngularJS Interview Questions [+With Example]

A great interview can help you to get insights into the developer's expertise and experience. If you plan to interview an AngularJs developer, you must require some research guide or gathered information. A researched material would help you examine the candidate's skills, knowledge, and experiences. With that in mind, we have prepared a step-by-step guide to help you find the AngularJs interview questions you should probably ask. Look at this informative guide to learn how to determine the interview questions before interviewing the candidate.

Principle Of Writing An Angular Developer Interview Questions

The mentioned guidelines will help the AngularJS development company to develop a list of interview questions-

The list of questions should be clear and concise. Try not to ask more than one question at a time.

Ask questions that elicit the most extended answers from the candidate. Avoid asking questions that can answer in one or two lines.

Do your analysis correctly, don't ask the candidate to do research or something.

Do not ask for opinions on the community in which they work, like- "How does the team manage it?" You will not get an optimistic answer.

5. Feel free to ask embarrassing questions to identify Angular developer skills and the ability to think.

6. Ask them about their experiences and what they have learned from their experiences.

Types of Angular developer Interview Questions

Here is the list of Angular developer interview questions that help you determine when and what to ask-

A. Credential verification questions

This type of question includes information like "What is your percentage in 10+2?" and "How many years have you worked with XYZ company?" Here you verified the information mentioned in their resume. It would help in verifying their credentials and verified information.

B. Opinion questions

These questions are being asked when you need to understand their inner self. Questions like "What would you do in this situation?" and "Tell me about your weaknesses" helps in analyzing how they would respond in such situations.

C. Behavioral questions

This question includes "Give an example of how you did that?" and "What process do you follow to determine better results?" It helps in measuring their past behaviors and their optimistic behavior.

D. Competency questions

The questions like "How can you determine the leadership skills?" or "What steps you'll take to finish this task" are being asked to examine their past behaviors with specific required competencies.

E. Nonsense questions

The questions like "What kind of cinema do you like?" and "Do you love exploring food?" ask to find out if they are capable of original thought. This question is asked to test your ability to think on your feet.

How to Write Interview Questions?

1. Identify and summarise the study's main research questions. Describe the broad knowledge domains that are needed to respond to these issues.

2. Create questions inside these critical categories, tailoring them to different types of respondents. Utilizing their knowledge and expertise is the main objective here.

3. Modify the interview's language based on the respondent (child, professional, etc.).

4. Be careful how you phrase your questions to encourage respondents to provide as detailed and accurate answers as possible.

5. Focus on "how" questions rather than "why" to know their background stories. "What inspired you to do this?"

6. Create probes to elicit more extensive and in-depth answers to important questions.

7. Start the interview with a "warm-up" question that will allow the respondent to answer more fully and readily (though not too long).

8. Consider the interview's logical flow. What subjects need to ask first? Adjust the asking pattern accordingly.

9. You should ask difficult and tricky questions at the end of the interview.

Top 3 AngularJS Interview Questions and Answers

1. What are the steps to test an AngularJS filter?

Inject the module with a filter.

Include mocks which the filter relies upon.

Add the filter using $filter('yourFilterName').

Insert your expectations.

2. Where should we implement the DOM manipulation in AngularJS?

DOM Manipulations don't exist in controllers, services, or anywhere. It only existed in directives.

3. What are Directives?

An AngularJS framework directive is a marker on a DOM element (such as an attribute, element name, comment, or CSS class) that instructs the HTML compiler ($compile) to alter the DOM element and its descendants or to attach a specific function to the DOM element.

Summing up

We hope you like the article. Next time you interview an Angular developer, don't forget to look out for these tips to ask the best questions to them. Good luck :)

Thanks for reading :)

If subclass (child class) has the same method as declared in the parent class, it is known as method overriding. In other words, redefined the base class methods in the derived class or child class. Rules for Method Overriding The method must have the same name as in the parent class The method must have the same parameter as in the parent class. There must be an IS-A relationship (inheritance). Example class NewPrinter extends Printer { doPrint(): any { super.doPrint(); console.log("Called Child class."); } doInkJetPrint(): any { console.log("Called doInkJetPrint()."); } } let printer: new () => NewPrinter; printer.doPrint(); printer.doInkJetPrint(); 32. What is "as" syntax in TypeScript? The as is the additional syntax for Type assertion in TypeScript. The reason for introducing the as-syntax is that the original syntax () conflicted with JSX. Example let empCode: any = 111; let employeeCode = code as number; When using TypeScript with JSX, only as-style assertions are allowed. 33. What is JSX? Can we use JSX in TypeScript? JSX is NOTHING BUT Javascript with a different extension. Facebook came up with this new extension so that they can distinguish from the XML-like implementation of HTML in JavaScript. JSX is an embeddable XML-like syntax. It is meant to be transformed into valid JavaScript. JSX came to popularity with the React framework. TypeScript supports embedding, type checking, and compiling JSX directly into JavaScript. To use JSX, we must do two things. Name the files with a .tsx extension Enable the jsx option 34. What are Ambients in TypeScripts and when to use them? Ambient declarations tell the compiler about the actual source code exist elsewhere. If these source codes do not exist at runtime and we try to use them, then it will break without warning. Ambient declarations files are like docs file. If the source changes, the docs need to be kept updated also. If the ambient declaration file is not updated, then we will get compiler errors. The Ambient declarations allow us to safely and easily use existing popular JavaScript libraries like jquery, angularjs, nodejs, etc. 35. What is a TypeScript Map file? TypeScript Map file is a source map file which holds information about our original files. .map files are source map files that let tools map between the emitted JavaScript code and the TypeScript source files that created it. Many debuggers can consume these files so we can debug the TypeScript file instead of the JavaScript file. TypeScript Questions and Answers Pdf Download Read the full article

300+ TOP AngularJS Interview Questions and Answers

ANGULARJS Interview Questions for freshers experienced :-

1. What Is AngularJs? AngularJs is a framework to build large scale and high performance web application while keeping them as easy-to-maintain. Following are the features of AngularJs framework. AngularJs is a powerful JavaScript based development framework to create RICH Internet Application (RIA). AngularJs provides developers options to write client side application (using JavaScript) in a clean MVC (Model View Controller) way. Application written in AngularJs is cross-browser compliant. AngularJs automatically handles JavaScript code suitable for each browser. AngularJs is open source, completely free, and used by thousands of developers around the world. It is licensed under the Apache License version 2.0. 2. What Is Data Binding In AngularJs? Data binding is the automatic synchronization of data between model and view components. ng-model directive is used in data binding. 3. What Is Scope In AngularJs? Scopes are objects that refer to the model. They act as glue between controller and view. 4. What Are The Controllers In AngularJs? Controllers are JavaScript functions that are bound to a particular scope. They are the prime actors in AngularJs framework and carry functions to operate on data and decide which view is to be updated to show the updated model based data. 5. What Are The Services In AngularJs? AngularJs come with several built-in services. For example $http service is used to make XMLHttpRequests (Ajax calls). Services are singleton objects which are instantiated only once in app. 6. What Are The Filters In AngularJs? Filters select a subset of items from an array and return a new array. Filters are used to show filtered items from a list of items based on defined criteria. 7. Explain Directives In AngularJs. Directives are markers on DOM elements (such as elements, attributes, css, and more). These can be used to create custom HTML tags that serve as new, custom widgets. AngularJs has built-in directives (ng-bind, ng-model, etc) to perform most of the task that developers have to do. 8. Explain Templates In AngularJs. Templates are the rendered view with information from the controller and model. These can be a single file (like index.html) or multiple views in one page using “partials”. 9. What Is Routing In AngularJs? It is concept of switching views. AngularJs based controller decides which view to render based on the business logic. 10. What Is Deep Linking In AngularJs? Deep linking allows you to encode the state of application in the URL so that it can be bookmarked. The application can then be restored from the URL to the same state.

AngularJS Interview Questions 11. What Are The Advantages Of AngularJs? Advantages of AngularJs: AngularJs provides capability to create Single Page Application in a very clean and maintainable way. AngularJs provides data binding capability to HTML thus giving user a rich and responsive experience. AngularJs code is unit testable. AngularJs uses dependency injection and make use of separation of concerns. AngularJs provides reusable components. With AngularJs, developer writes less code and gets more functionality. In AngularJs, views are pure html pages, and controllers written in JavaScript do the business processing. AngularJs applications can run on all major browsers and smart phones including Android and iOS based phones/tablets. 12. How To Implement Internationalization In AngularJs? AngularJs supports inbuilt internationalization for three types of filters currency, date and numbers. We only need to incorporate corresponding js according to locale of the country. By default it handles the locale of the browser. For example, to use Danish locale, use following script 13. What Is Internationalization? Internationalization is a way to show locale specific information on a website. For example, display content of a website in English language in United States and in Danish in France. 14. On Which Types Of Component Can We Create A Custom Directive? AngularJs provides support to create custom directives for following type of elements. Element directives − Directive activates when a matching element is encountered. Attribute − Directive activates when a matching attribute is encountered. CSS − Directive activates when a matching css style is encountered. Comment − Directive activates when a matching comment is encountered. 15. Which Components Can Be Injected As A Dependency In AngularJs? AngularJs provides a supreme Dependency Injection mechanism. It provides following core components which can be injected into each other as dependencies. value factory service provider constant 16. Is AngularJs Extensible? Yes! In AngularJS we can create custom directive to extend AngularJS existing functionalities. Custom directives are used in AngularJS to extend the functionality of HTML. Custom directives are defined using “directive” function. A custom directive simply replaces the element for which it is activated. AngularJS application during bootstrap finds the matching elements and do one time activity using its compile() method of the custom directive then process the element using link() method of the custom directive based on the scope of the directive. 17. What Is Constant? constants are used to pass values at config phase considering the fact that value cannot be used to be passed during config phase. mainApp.constant(“configParam”, “constant value”); 18. What Are The Differences Between Service And Factory Methods? factory method is used to define a factory which can later be used to create services as and when required whereas service method is used to create a service whose purpose is to do some defined task. 19. What Is Factory Method? Using factory method, we first define a factory and then assign method to it. var mainApp = angular.module(“mainApp”, ); mainApp.factory(‘MathService’, function() { var factory = {}; factory.multiply = function(a, b) { return a * b } return factory; }); 20. What Is Service Method? Using service method, we define a service and then assign method to it. We’ve also injected an already available service to it. mainApp.service(‘CalcService’, function(MathService) { this.square = function(a) { return MathService.multiply(a,a); } }); 21. What Is A Service? Services are JavaScript functions and are responsible to do specific tasks only. Each service is responsible for a specific task for example, $http is used to make ajax call to get the server data. $route is used to define the routing information and so on. Inbuilt services are always prefixed with $ symbol. 22. What Is Use Of $routeprovider In AngularJs? $routeProvider is the key service which set the configuration of urls, maps them with the corresponding html page or ng-template, and attaches a controller with the same. 23. What Is $rootscope? Scope is a special JavaScript object which plays the role of joining controller with the views. Scope contains the model data. In controllers, model data is accessed via $scope object. $rootScope is the parent of all of the scope variables. 24. How To Make An Ajax Call Using AngularJs? AngularJS provides $http control which works as a service to make ajax call to read data from the server. The server makes a database call to get the desired records. AngularJS needs data in JSON format. Once the data is ready, $http can be used to get the data from server in the following manner: function studentController($scope, $http) { var url = “data.txt”; $http.get(url).success( function(response) { $scope.students = response; }); } 25. How To Validate Data In AngularJs? AngularJS enriches form filling and validation. We can use $dirty and $invalid flags to do the validations in seamless way. Use novalidate with a form declaration to disable any browser specific validation. Following can be used to track error. $dirty − states that value has been changed. $invalid − states that value entered is invalid. $error − states the exact error. 26. How Angular.module Works? angular.module is used to create AngularJS modules along with its dependent modules. Consider the following example: var mainApp = angular.module(“mainApp”, ); Here we’ve declared an application mainApp module using angular.module function. We’ve passed an empty array to it. This array generally contains dependent modules declared earlier. 27. Explain Ng-click Directive? ng-click directive represents a AngularJS click event. In below example, we’ve added ng-click attribute to a HTML button and added an expression to updated a model. Then we can see the variation. Total click: {{ clickCounter }} Click Me! 28. Explain Ng-hide Directive? ng-hide directive hides a given control. In below example, we’ve added ng-hide attribute to a HTML button and pass it a model. Then we’ve attached the model to a checkbox and can see the variation. Hide Button Click Me! 29. Explain Order By Filter? orderby filter orders the array based on provided criteria. In below example, to order subjects by marks, we’ve used orderBy marks. Subject: Read the full article
