PICTURE THIS: DATA SPLIT

Train 70%Val 15%Test 15%

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

Simple meaning

Docker packages code, system libraries, and Python dependencies into an image that runs the same on a laptop, CI, and a cluster.

WHY — Docker instead of guessing?

Why interviewers care about Docker:

Docker 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
Docker packages code, system
libraries, and Python dependencies into an image that runs the same on a laptop, CI, and a cluster.
2
That kills the it
works on my machine problem for training and serving.
3
ML stacks are especially
fragile because of CUDA, BLAS, and pin versions.
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.
