I was interviewed in Aug 2024.
Software development design patterns are reusable solutions to common problems encountered in software design.
Design patterns help in creating maintainable, scalable, and efficient software.
Singleton design pattern ensures a class has only one instance and provides a global point of access to it.
Example: Implementing a singleton class in Java -
public class Singleton { private static Singleton instance; private Singleto...

Types of deployments include blue-green, canary, rolling, and immutable.
Blue-green deployment involves running two identical production environments and switching between them.
Canary deployment gradually rolls out changes to a small subset of users before deploying to the entire infrastructure.
Rolling deployment updates a few instances at a time, ensuring continuous availability.
Immutable deployment creates new instanc
Blue Green Deployment is a software release strategy that reduces downtime and risk by running two identical production environments.
In Blue Green Deployment, one environment (blue) is live and serving production traffic while the other (green) is idle and ready to be switched to at any time.
This strategy allows for zero downtime deployments, as the switch between blue and green environments can be done seamlessly.

Vector databases store data in a vector format, allowing for efficient querying and analysis of high-dimensional data.
Vector databases use vectors to represent data points in a multi-dimensional space.
They are commonly used in machine learning and data science applications for tasks like similarity search and clustering.
Examples of vector databases include Faiss, Annoy, and Milvus.
Yes, I can solve a coding problem in a language I don't know with Google search.
Utilize Google search to understand syntax and concepts in the unfamiliar language
Break down the problem into smaller parts and search for solutions to each part
Refer to online resources, forums, and documentation for guidance
Practice writing and testing code snippets in the new language before attempting the full solution
Use regex to extract location and shop name from transaction string.
Use regular expressions to match patterns for location and shop name.
Look for keywords like 'at', 'from', 'in' to identify location.
Consider variations in transaction strings and account for them in regex patterns.
Example: 'Spent $50 at Starbucks Coffee' -> Location: Starbucks Coffee, Shop Name: Starbucks Coffee

Singleton design pattern restricts the instantiation of a class to one object.
Ensures only one instance of a class exists in the system
Provides a global point of access to that instance
Used when only one instance of a class is required throughout the system
Example: Database connection manager, Logger class
OOP concepts include class, encapsulation, inheritance, and polymorphism.
Class is a blueprint for creating objects with shared properties and methods.
Encapsulation is the practice of hiding implementation details and exposing only necessary information.
Inheritance allows a class to inherit properties and methods from a parent class.
Polymorphism allows objects to take on multiple forms or behaviors depending on the cont...
