PICTURE THIS: HOW TO EXPLAIN IT

IdeaLatency and Throughput

HowWhat happens inside

Why they askShows real use

Simple meaning

Throughput is how many predictions you complete per second, often QPS.

WHY — Latency and Throughput instead of guessing?

Why interviewers care about Latency and Throughput:

Latency and Throughput questions

separate people who only read docs from people who shipped.

Keep it short, concrete,

and tied to MLOps work.

Stay structured

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
Throughput is how many
predictions you complete per second, often QPS.
2
High throughput can come
from batching, more replicas, or more efficient runtimes.
3
A system can have
high throughput and still fail a latency SLO if tails are fat.
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.
