PICTURE THIS: HOW TO EXPLAIN IT

IdeaConcept Drift

HowWhat happens inside

Why they askShows real use

Simple meaning

A UPI fraud model may still see similar transaction amounts, but fraudsters change mule patterns after a new bank rule.

WHY — Concept Drift instead of guessing?

Why interviewers care about Concept Drift:

Concept Drift 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?

2

map to different fraud labels.
3
That is concept drift
and needs new labels and often new features.
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.
