LLMAnswer with sources

Simple meaning

Availability and p99 latency, plus data freshness, prediction coverage, and a quality SLO on a delayed metric with an error budget.

WHY — Monitoring instead of guessing?

Why interviewers care about Monitoring:

Monitoring questions separate people

who only read docs from people who shipped.

Keep it short, concrete,

and tied to MLOps work.

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:

1

plus data freshness, prediction coverage, and a quality SLO on a delayed metric with an error budget.
2
You might budget a
maximum weekly PSI or a floor on slice recall.
3
Error budgets decide whether
you ship new models or freeze and stabilize.
4
Give an example
One tiny concrete case you can say aloud.
5
Common mistake
What juniors usually get wrong.
6
Close
When you pick this over the alternative.
