  • Q3. Arrow function vs Regular function
  • Ans. 

    Arrow functions are concise and do not bind their own 'this' value, while regular functions have their own 'this' value and can be used as constructors.

    • Arrow functions have a more concise syntax compared to regular functions.

    • Arrow functions do not have their own 'this' value, they inherit it from the parent scope.

    • Regular functions have their own 'this' value, which can be useful for object-oriented programming and cons

  • Ans. 

    Subject vs BehaviourSubject in Angular

  • Q6. Custom pipes and how to use it in html
  • Ans. 

    Custom pipes in Angular are used to transform data in templates.

    • Custom pipes are created using the @Pipe decorator in Angular.

    • To use a custom pipe in HTML, you need to include it in the declarations array of the NgModule.

    • You can pass parameters to custom pipes in HTML using the pipe symbol (|).

    • Example: {{ value | customPipe:param1:param2 }}

  • Answered by AI
  • Q7. What is ng-template, ng-content and ng-container
  • Ans. 

    ng-template, ng-content, and ng-container are Angular structural directives used for template rendering and content projection.

    • ng-template is used to define a template that can be rendered conditionally or multiple times.

    • ng-content is used for content projection, allowing the insertion of content from a parent component into a child component.

    • ng-container is a grouping element that doesn't interfere with styles or layo...

  • Answered by AI
  • Q8. Explain ForkJoin and parallel execution
  • Ans. 

    ForkJoin is an operator in Angular that allows for parallel execution of multiple observables.

    • ForkJoin combines the values from multiple observables and emits them as an array when all observables complete.

    • It waits for all observables to complete and then emits the combined result.

    • Example: forkJoin([observable1, observable2]).subscribe(result => console.log(result));

  • Answered by AI
  • Q9. Wildcard routes and it's syntax
  • Ans. 

    Wildcard routes in Angular allow for handling unknown routes and redirecting to a default route.

    • Wildcard route is denoted by '**' in the route configuration.

    • It is typically used at the end of the route configuration to handle unknown routes.

    • Example: { path: '**', redirectTo: '/404' }

    • Implement error handling logic in the catch block to handle different types of errors

    • Display user-friendly error messages to inform users about the issue

Interview Preparation Tips

General Tips: Be pretty confident on the current project you are working on. It's ok that you do not know the complete technology but you should have the complete picture of stuff you are working on. Be clear as to why are using specific technology for your project and not the other one. For example, i worked on azure and drilled my way to understand the edge azure has over aws. I did good work onto why are we using hive language and azure data ware house for our project instead of using u-sql and azure SQL data base. Do not bluff, better be humble to accept that we are not fully aware of something and given a chance to work on, we will. And last thing, smile and appreciate the effort put in by interviewer.
