ReactJs life cycle is a series of methods that are invoked in a specific order when a component is created, updated or destroyed.
Mounting: constructor(), static getDerivedStateFromProps(), render(), componentDidMount()
Updating: static getDerivedStateFromProps(), shouldComponentUpdate(), render(), getSnapshotBeforeUpdate(), componentDidUpdate()
Unmounting: componentWillUnmount()
Error Handling: static getDerivedStateFromE...
The version of .NET Core used is [insert version number here].
The current version of .NET Core is 3.1.
It is important to specify the version used in order to ensure compatibility with other software components.
Examples of version numbers include 2.1, 2.2, and 3.0.
Dependency Injection is a design pattern used to achieve loose coupling between objects and their dependencies.
DI is used to provide objects with their dependencies rather than having them create their own.
It helps in achieving loose coupling between objects and their dependencies.
DI can be implemented using constructor injection, property injection, or method injection.
In .NET Core, DI is built-in and can be used by r...
Clustered index determines the physical order of data in a table while non-clustered index creates a separate structure.
Clustered index is faster for retrieving large amounts of data in a sequential order.
Non-clustered index is faster for retrieving small amounts of data in a random order.
A table can have only one clustered index but multiple non-clustered indexes.
Clustered index is automatically created on the primary...

Classloaders are responsible for loading classes into the JVM at runtime.
Java has three built-in classloaders: bootstrap, extension, and system.
Custom classloaders can be created to load classes from non-standard sources.
Classloaders follow a delegation model, where they first delegate to their parent classloader before attempting to load the class themselves.
Classloaders can be used for dynamic class loading and hot-s...
I applied via Referral and was interviewed in Jul 2020. There were 3 interview rounds.
The sliding window technique efficiently finds Pythagorean triplets in an array using two pointers.
Sort the array to facilitate the two-pointer approach. Example: [3, 1, 4, 6, 5] becomes [1, 3, 4, 5, 6].
Iterate through the array, fixing one element and using two pointers for the remaining elements.
For each fixed element, check if the sum of squares of the two pointers equals the square of the fixed element.
If a triplet...

Abstract classes allow partial implementation; interfaces define contracts without implementation.
Abstract classes can have both abstract and concrete methods, while interfaces can only have abstract methods (until Java 8).
An abstract class can have member variables, whereas an interface cannot (it can only have constants).
A class can inherit from only one abstract class but can implement multiple interfaces.
Example: I...
OOP in C# is a programming paradigm based on objects, encapsulating data and behavior for modular and reusable code.
Encapsulation: Bundling data and methods that operate on the data within a single unit (class). Example: class 'Car' with properties like 'Speed' and methods like 'Accelerate()'.
Inheritance: Mechanism to create a new class based on an existing class, promoting code reuse. Example: 'ElectricCar' inherits f...

Building a RAG application requires careful consideration of data sources, user experience, and performance optimization.
Identify reliable data sources: Ensure the data used for retrieval is accurate and up-to-date, e.g., using APIs from trusted providers.
Optimize retrieval algorithms: Implement efficient algorithms to minimize latency, such as caching frequently accessed data.
Design user-friendly interfaces: Create in...
