WHY — C# instead of guessing?

Why interviewers care about C#:

C# questions separate people

who only read docs from people who shipped.

Keep it short, concrete,

Stay structured

Name the idea, why it exists, then one short example.

Close cleanly

End with when you use it and one common pitfall.

    is a classic leak in interviews.

  4. 4
    Give an example

    One tiny concrete case you can say aloud.
