Explain the design patterns used in your project.

Question

Accepted Answer

I have used the Singleton and Factory design patterns in my project.

Singleton pattern is used to ensure only one instance of a class is created and provide a global point of access to it.
Factory pattern is used to create objects without exposing the creation logic to the client and refer to newly created object using a common interface.

First of all go through the basics of deisgn patterns first and compare it with your project structure. Ex: If you are using Spring Boot, you can say dependency patterns used are Singleton, Dependency Injection, MVC, Service Oriented architecture etc. Toatlly depends on what project you are working on. If they ask about examples of Publisher Subscriber model, say Youtube channels. Like this you can map concepts to real workd examples and prepare. Do well. Thanks.. :)
