8 steps to prepare for your Netflix software engineer interview#
1. Study the Netflix culture deck#
Many software engineers make the mistake of underestimating the importance of their culture fit in the interview process. Make no mistake – Netflix cares, and so should you.
“Our core philosophy is people over process. More specifically, we have great people working together as a dream team. With this approach, we are a more flexible, fun, stimulating, creative, collaborative and successful organization.” – From the Netflix culture memo
If you haven’t heard from the recruiter yet, they’ll tell you that you need to read the culture deck before your initial phone screen. Even for technical roles, your culture fit is weighs heavily on your candidacy, from start to finish.
Culture memo: Current signals & how to show them#
Netflix keeps refining its culture memo. Read the latest version and be ready to map stories to values like judgment, selflessness, courage, candor, curiosity, inclusion, resilience, and the “dream team” ethos. The much-discussed “keeper test” is now framed with more nuance, but the spirit remains: high bar, continuous feedback, and owning outcomes. In interviews, demonstrate that you seek context, not control, and make high-quality decisions amid ambiguity.
Behavioral prep tip: prepare 6–8 STAR stories you can rotate:
-
A hard trade-off (cost vs reliability) you owned and how you measured impact.
-
A proactive correction—when you disagreed and changed a plan with data and candor.
-
Raising the bar—mentoring, docs, or automation that improved team velocity.
-
Inclusion in action—how you ensured diverse voices shaped a design.
Keep stories concise, numbers-forward, and candid about misses and follow-ups.

2. Connect your past experience with Netflix culture and values#
Look at your resume and start connecting dots between your past experience and Netflix’s values. You’ll want to tell a story about how your past accomplishments demonstrate your alignment with Netflix’s cultural values, such as leadership and candor.
Phone interviews are the very first steps in the interview process. There are two phone calls, where the recruiter and hiring manager will primarily ask behavioral questions to assess your culture fit. All they’ll have in hand is your resume and perhaps your LinkedIn profile. By targeting details in your resume, you’ll build a more tangible story of your culture fit.
Tip: Practice talking about your accomplishments out loud. As opposed to writing a cover letter and resume, sometimes verbalizing our strengths is the hardest part.
3. Prepare to grok the system design interview#
Netflix’s technical interview questions aren’t like LeetCode questions. Instead, they’re more open-ended, with the aim of assessing your design skills and subject matter expertise. Since Netflix mainly hires senior developers, this emphasis on design skills is in line with industry expectations. This means you’ll want to study system design principles and practice system design interview questions.
System design interviews ask open-ended questions such as “Design the Uber backend”, “Design TinyURL," or “Design an API.” While you may not be asked this particular question, practicing designing video streaming services such as Netflix will surely be good to know too! Throughout the interview, you’ll share your thought process and whiteboard solutions to demonstrate how you apply design principles to real-world problems.
Aim where Netflix aims: System Design with a Netflix flavor#
Expect prompts that mirror Netflix’s platform realities. Practice articulating:
-
Global content delivery (CDN/Open Connect). Partitioning by geography, cache-fill strategies, cache invalidation, peering, cost controls, and how you monitor cache hit ratios.
-
Fault-tolerant streaming. Multi-region active-active, graceful degradation, resilient manifest fetch, adaptive bitrate (ABR), and chaos/latency injection to verify SLOs.
-
Personalization & search. Ranking architecture, feature stores, batch vs streaming updates, and guardrails for fairness/latency.
-
Low-latency APIs. Tail latency, read-path optimizations (fan-out/fan-in), backpressure, and time-bounded fallbacks.
Interviewers often ask, “How would this fail, and what would you build to see it coming?” Bring observability (RED metrics, tracing), safe deploys (canary/blue-green), and resilience (timeouts, retries with jitter, circuit breakers, bulkheads). Make concrete trade-offs: “We accept 1% stale recommendations to bound p99 under 150 ms.”

4. Study the fundamentals in one programming language#
Netflix’s technical questions are focused on design, but you’ll still need to show your problem-solving skills with more basic programming concepts. Unless the job description says otherwise, we recommend focusing on a strong working knowledge of one programming language. Make sure to study various programming basics in that language, including design patterns and data structures and algorithms, such as binary search trees and linked lists.
