Recommended next: your first attempt
Do the Hiring manager and project depth round.
A complete first attempt shows where you stand before any narrow practice starts.
The loop
Pick a round to see what it asks of you and where you stand on it.
Hiring manager and project depth
Demonstrate independent engineering judgment through a project’s constraints, decisions and consequences.
Behavioral · 45 minSet up this round
Not tried yetNo attempt yet.
What strong sounds like
- Explain what you decided and why the problem mattered.
- Compare plausible approaches and the information available at the time.
- Connect the work to a measurable production or customer outcome.
- Explain the part you would change and the evidence that changed your view.
Expect to be pushed on
Who disagreed, and what did they know that you did not?
How did you know the decision was working?
Shapes of problem you may get
- A production project with a difficult architecture decision
- A decision made with substantial autonomy
- An unpopular technical recommendation
How to prepare
- 01
Select one owned service
Choose a service you owned. Record its user or production problem, architecture, constraints, two realistic alternatives, decision evidence, measurable result and one later change.
The round requires project depth. A single service gives you enough detail to explain judgment without turning the discussion into a technology list.
Suggested approach
- 02
Rehearse decision timing
Write what you knew before the decision, what you learned later and how that changed your view. Include one disagreement and how you sought useful input.
This prevents hindsight from replacing the information available at the time and makes collaboration part of autonomy.
Suggested approach
- 03
Connect judgment to Netflix context
Read the Culture Memo sections on Judgment, Candor and Informed Captains. Mark where your example shows ownership, dissent and responsibility for the outcome.
Netflix’s current Culture Memo emphasizes responsible autonomy, candor and continuous improvement. This round can test those behaviors through project evidence.

Then try the round
You have one service example with its decision timeline, alternatives, evidence, result, disagreement and changed judgment written in brief notes.
Resources to focus on
- Netflix Culture Memo - Careers at Netflix
Read “Judgment,” “Candor,” “People Over Process,” “Informed Captains,” and “Great and Always Better.”
Use the memo to check that your project example shows informed ownership, dissent and improvement.
A first attempt takes the full 45 minutes.
What this loop tests
Prepare to reason like the owner of a production service: implement practical components, evolve a distributed design, and defend the decisions behind your past work. Netflix’s culture discussion tests judgment, candor, and responsibility. Pair coding practice with concurrency, caching, failure recovery, and measurable trade-offs. Bring examples where you made a difficult call, invited dissent, changed your mind, and improved the outcome.
They reward
- Independent, informed judgment
- Candor that improves decisions
- Practical production depth
- Responsibility for outcomes
What to avoid
- Do not imply autonomy means avoiding collaboration.
- Do not present hindsight as information you had at the time.
- Do not build production scaffolding before the core logic.
- Do not treat a lock as an explanation of the protected invariant.
- Do not mistake practical framing for permission to hand-wave algorithms.
How sure we are
Worth redoing if you hear something from the recruiter that contradicts this.
Confirmed · 8
- Netflix’s current Culture Memo emphasizes responsible autonomy, candor and continuous improvement.
- Netflix engineering spans distinct infrastructure, member-product and business-system domains.
- A coding-screen participant describes implementing cache TTL, adding LRU, then discussing concurrent access.
- A March 2025 candidate describes coding, problem-solving, design, hiring-manager and culture interviews.
Likely · 2
- Senior backend practice should test concurrency, failure recovery and operational cost within one concrete service.
- Culture preparation should demonstrate how personal judgment, dissent and feedback changed a real outcome.
Worth asking them
Questions that close the gaps above.
What context does the team share so engineers can make independent decisions?
Which reliability or cost trade-off is currently unresolved?
How does the team invite dissent before committing to a direction?
