Dependency injection service lifetime determines how long a service instance will be available for use.
Service lifetime can be scoped to a single request, a session, or the entire application
Transient lifetime creates a new instance every time it is requested
Singleton lifetime creates a single instance for the entire application
Scoped lifetime creates a single instance for each request or session
Lifetime can affect per
Middleware in ASP.NET Core is a software component that sits between the web server and the application and handles requests and responses.

Deploying an app in Kubernetes involves creating a deployment configuration, defining pods, services, and managing resources.
Create a deployment configuration file specifying the app's image, ports, and replicas
Define pods to run the app containers
Create services to expose the app internally or externally
Manage resources such as CPU and memory limits for optimal performance
Interfaces in Golang allow for defining behavior without specifying implementation details.
Interfaces are a collection of method signatures.
A type satisfies an interface if it implements all the methods in the interface.
Interfaces allow for polymorphism in Golang.
Example: type Writer interface { Write([]byte) (int, error) }
Example: type MyWriter struct {} func (mw MyWriter) Write(data []byte) (int, error) { return len(
Goroutines are lightweight threads managed by Go runtime, allowing concurrent execution of functions.
Goroutines are created using the 'go' keyword followed by a function call.
They are multiplexed onto multiple OS threads by the Go runtime.
Example: go func() { fmt.Println('Hello, goroutine!') }
Goroutines are used for concurrent programming in Go, enabling parallelism.
I applied via Job Portal
Use SQL query with GROUP BY and HAVING clause to find duplicates in a table.
Use GROUP BY clause to group rows with same values
Use HAVING clause to filter out groups with count greater than 1
Example: SELECT column_name, COUNT(*) FROM table_name GROUP BY column_name HAVING COUNT(*) > 1
Node.js event loop is a mechanism that allows Node.js to perform non-blocking I/O operations asynchronously.
Event loop is responsible for handling asynchronous operations in Node.js.
It allows Node.js to perform multiple operations simultaneously without blocking the execution.
Event loop continuously checks the event queue for new events and executes them in a non-blocking manner.
Callbacks are used to handle the complet
- Basic data structures questions.
- Node.js specific questions.
Angular is a popular open-source front-end web application framework developed by Google.
Angular is used for building dynamic web applications.
It allows for the creation of single-page applications.
Angular uses TypeScript for building applications.
It provides features like data binding, dependency injection, and routing.
Angular has a large community and ecosystem of libraries and tools.
Examples: AngularJS, Angular 2, A
Routing is the process of selecting a path for network traffic to travel from source to destination.
Routing involves determining the best path for data packets to travel through a network
Routers use routing tables to make decisions on where to send data packets
Routing protocols like OSPF and BGP help routers communicate and update routing information
There are various types of forms, such as physical forms, digital forms, legal forms, etc.
Physical forms: Paper-based forms that are filled out by hand.
Digital forms: Electronic forms that are filled out online or through software.
Legal forms: Forms used for legal purposes, such as contracts or agreements.
Lazy loading in Angular is a technique used to load modules only when they are needed, improving performance by reducing initial load time.
Lazy loading helps in reducing the initial bundle size of the application by loading modules asynchronously.
It improves the performance of the application by only loading the modules that are required at a particular time.
Lazy loading is achieved by using the loadChildren property i...
The rxjs operator in Angular is used for reactive programming and handling asynchronous data streams.
RxJS operators are functions that build on the observables foundation to enable sophisticated manipulation of asynchronous data streams.
Operators can be used to filter, transform, combine, and more on observables.
Example: map(), filter(), mergeMap(), switchMap()
Testing frameworks are tools that help automate the process of testing software applications.
Testing frameworks provide a structure for writing and executing test cases.
They offer features like test data management, test case organization, and reporting.

Factory pattern creates objects without specifying the exact class of object...
Delegates are type-safe function pointers in C# used for implementing callbacks. async/await is used for asynchronous programming in C#.
Delegates in C# are similar to function pointers in C or C++. They allow methods to be passed as parameters to other methods.
Async/await in C# is used for asynchronous programming, allowing methods to run asynchronously without blocking the main thread.
Delegates can be used with async/
An interceptor is a design pattern commonly used in software development to capture and manipulate requests and responses.
Interceptors can be used for logging, authentication, authorization, caching, error handling, etc.
In Angular, interceptors can be used to modify HTTP requests before they are sent and responses before they are received.
In Spring framework, interceptors can be used to intercept client requests and se
Authentication is the process of verifying the identity of a user or system.
Authentication involves confirming the identity of a user through credentials such as passwords, biometrics, or security tokens.
Common methods of authentication include single-factor authentication (e.g. password) and multi-factor authentication (e.g. password + SMS code).
Authentication can be achieved through protocols like OAuth, OpenID, SAML...
Services in Android are components that run in the background to perform long-running operations.
Services can be used to play music in the background while the user interacts with other apps.
They can also be used to download files from the internet even when the app is not in the foreground.
Services can run indefinitely or be scheduled to run at specific times.
They can communicate with other components using broadcasts
