Netflix Data Engineering: Start Here
Clarify scope, show the end-to-end journey, and position the data-engineering boundary before any deep dive.
Start here
Design the shared data platform
Keep the opening light: what data comes in, what the platform does, and who it serves.

Shared data platform
Accept event streams and CDC once, then shape them into both fast and historical data products.

Consumers
I would design the member-interaction data platform: events and CDC flow into one shared platform, then serve fast monitoring, personalization, analytics, training, and reporting consumers with different freshness needs.
Requirements
Keep the requirements light
Use these as a quick checklist. Select any card for its meaning and a Netflix example.
Scope
Go deep on one clean slice
Member interaction data is the main design. The rest stays extension-only.
In scope
playback, browse, search, impression, click, QoE telemetry
real-time monitoring and personalization signals
historical analytics and recommendation training data
CDC from operational stores
Mention only
video encoding
Open Connect internals
payment processing internals
recommendation model design
Freshness
Real-time needs numbers
Different consumers need very different freshness targets.

Short handoff
One line is enough before estimation.
“We have the platform boundary, the main consumers, the requirement shape, and the freshness targets. Next I would size the scale before drawing detailed architecture.”

Numbers are interview assumptions, not real Netflix internal figures.
