Sample Go Questions

Practice these and more

Concurrency

Implement a worker pool pattern with N workers processing jobs from a channel. Handle graceful shutdown.

Channels

What's the difference between buffered and unbuffered channels? When would you use each? What happens on a closed channel?

Interfaces

How does Go's interface implementation differ from other languages? Explain the empty interface and type assertions.

Design

Design a rate limiter using Go. Consider using channels or the sync package. Discuss trade-offs.
