Concrete Creators (FileLoggerFactory and ConsoleLoggerFactory):?

Short answer: These subclasses of LoggerFactory override the CreateLogger method to return the appropriate logger type (either FileLogger or ConsoleLogger). FileLoggerFactory: public class FileLoggerFactory : LoggerFactory

Example code

{
public override ILogger CreateLogger() => new FileLogger();
} ConsoleLoggerFactory: public class ConsoleLoggerFactory : LoggerFactory
{
public override ILogger CreateLogger() => new ConsoleLogger();
}

Real-world example (ShopNest)

ShopNest’s NotificationFactory creates Email or SMS senders based on user preference.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
