PICTURE THIS: DATA SPLIT

Train 70%Val 15%Test 15%

Fit on train, tune on val, report on test once.

Simple meaning

Each version should store Git SHA, DVC or table snapshot IDs, training run ID, metrics, and the serving image digest.

WHY — Model Registry instead of guessing?

Why interviewers care about Model Registry:

Model Registry 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
Each version should store
Git SHA, DVC or table snapshot IDs, training run ID, metrics, and the serving image digest.
2
That graph lets you
answer which data produced Friday's production model.
3
Without lineage, audits and
rollbacks become archaeology.
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.
