LLMAnswer with sources
Simple meaning
Static links code into the binary
WHY — Build instead of guessing?
Why interviewers care about Build:
They want a clean
contrast on Build, not two memorised paragraphs.
Say what changes for
the developer, then one case where picking wrong hurts.
Stay structured
Name the idea, why it exists, then one short example.
Close cleanly
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1Static links code into
the binary
- 2Why it exists
shared loads at runtime.
- 3Shared saves disk and
memory across processes.
- 4Give an example
ABI stability matters for shared.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.
EXAMPLE — See it in action
Here's a short line you can speak, broken into clear beats:
Say this line
“Shared saves disk and memory across processes.”

Key takeaway
Static links code into the binary shared loads at runtime.
