A Go interview is rarely about syntax alone.

Yes, you should know how slices work, how goroutines and channels behave, how interfaces compose, and how errors propagate. But for mid and senior roles, interviewers are looking for something deeper:

Can you build correct software under real constraints?

Can you reason about trade-offs and explain them in plain language?

Can you debug production issues, prevent goroutine leaks, design simple APIs, write tests, and explain why you chose one approach over another?
