NEC Senior Software Engineer Interview Questions and Answers

Angular offers advantages such as two-way data binding, dependency injection, and modular architecture.

• Two-way data binding allows automatic synchronization of data between the model and the view, reducing the need for manual DOM manipulation.

• Dependency injection helps manage dependencies and promotes code reusability by allowing components to be easily injected with their dependencies.

• Modular architecture enables deve...read more

ngModel is a directive in AngularJS that binds the value of HTML controls to application data.

• ngModel is used for two-way data binding in AngularJS.

• It can be used with input, select, textarea, and custom form controls.

• Example:

Async/await is a feature in programming that allows asynchronous code to be written in a synchronous manner.

• Async/await is a way to write asynchronous code in a more synchronous style.

• It is used in languages like JavaScript to handle asynchronous operations.

• Async functions return a Promise, which allows them to be awaited.

• Await keyword is used to pause the execution of an async function until a Promise is settled.

Implementing CI/CD involves automating the process of integrating code changes and deploying them to production.

• Set up a version control system like Git to track changes

• Use a continuous integration tool like Jenkins to automatically build and test code

• Implement automated testing to ensure code quality

• Use a continuous deployment tool like Ansible or Docker to deploy code changes

• Integrate monitoring and alerting to track

Redux is a predictable state container for JavaScript apps.

• Redux is a state management library commonly used with React.

• It follows a unidirectional data flow pattern.

• Actions are dispatched to update the state through reducers.

• State changes are handled immutably.

• Selectors can be used to access specific parts of the state.

• Middleware can be used for side effects like async operations.

• Example: Dispatching an action to add

Hooks in React are functions that let you use state and other React features in functional components.

• Hooks were introduced in React 16.8 to allow functional components to have state and lifecycle methods.

• useState() is a hook that allows you to add state to functional components.

• useEffect() is a hook that lets you perform side effects in functional components.

• Custom hooks are reusable functions that can contain statefu

Calling stored procedures in code first approach and code first migration

• Use Entity Framework to call stored procedures in code first approach

• Create a DbContext class with DbSet properties for entities and DbSets for stored procedures

• Use the Database.SqlQuery method to execute stored procedures in code first migration

Projects are specific tasks or assignments that require a team to work together to achieve a common goal.

• Projects involve a defined scope, timeline, and budget.

• They often require collaboration among team members with different skill sets.

• Projects can range from developing software applications to implementing new processes or systems.

• Examples: Developing a mobile app, implementing a new CRM system, conducting a market
