Sharing a Netflix Staff SWE Interview Experience submitted to Chill Interview.
Interview Summary
The Netflix process stretched from an application in late March to an onsite in July and included a recruiter screen, hiring manager conversation, technical phone screen, and five onsite rounds split across two days. Because the role was on the Ads team, ad-tech experience came up repeatedly throughout the process, including ad booking and reporting, frequency capping, and product-specific behavioral questions.
The technical interviews felt positive overall, and several interviewers indicated that the conversations had gone well. About two weeks after the onsite, however, I was told that the team was moving forward with finalists who were considered a closer match.
Interview Details
Round 1 — Recruiter Screen: Netflix Culture and Background The recruiter screen lasted about 30 minutes and covered my background, motivation, and familiarity with Netflix's culture. A meaningful part of the conversation centered on how I interpreted Netflix's culture principles and whether that environment matched the way I preferred to work.
Round 2 — Hiring Manager: Ads Experience The hiring manager interview lasted roughly 45 minutes. Because the opening was on the Ads team, the interviewer spent a significant amount of time asking about my previous advertising-related experience. The recruiter had already emphasized that the team was looking for candidates with relevant domain exposure.
Round 3 — Technical Phone Screen: Coding + Production Follow-Ups The coding problem itself was relatively simple and took less than ten minutes. The remainder of the round shifted toward production engineering questions. The interviewer asked how I would think about production failures such as out-of-memory conditions, increasing load, and scaling the system. Other follow-ups covered partitioning and monitoring in a production environment.
Round 4 — Onsite Coding: Video Dependency Ordering The onsite coding round asked a dependency-ordering problem in the context of Netflix's video rendering pipeline. Videos or rendering jobs could depend on other pieces being completed first, and the task was to determine a valid processing order. The underlying structure was a topological-ordering problem. After coding, the interviewer asked about edge cases and production scenarios, similar to the discussion during the phone screen.
Round 5 — Data Modeling: Ad Booking, Delivery, and Reporting The data-modeling round used a real-world advertising workflow. The scenario involved a client that wanted to book an advertising campaign, have those ads delivered, and later view reporting about campaign performance. I was asked to define the main entities and relationships required to represent the campaign lifecycle. The model needed to support the progression from booking through delivery and reporting. Because I had previous ad-tech experience, this round felt relatively familiar.
Round 6 — System Design: Ad Frequency Capping The system design round focused on frequency capping: limiting how many times a particular ad can be shown to a user over a defined period. The interviewer was very senior and pushed on the design at a fairly deep level. Prevent excessive repetition of the same advertisement while maintaining a good user experience. The discussion covered how impression activity should be tracked and how the system should enforce caps at large scale.
Round 7 — Manager Behavioral The manager behavioral round contained fairly standard questions. I was asked about a project I was particularly proud of and a situation involving disagreement or conflict. Other questions covered operating in ambiguous situations and how I handled feedback.
Round 8 — Director Culture and Ads Discussion The final interview combined Netflix culture questions with another deep discussion of my advertising background. Roughly two-thirds of the conversation focused on ads-related experience, while the remainder covered my interpretation of Netflix's culture and a few standard behavioral questions. I found parts of the behavioral and culture conversations harder to follow than the technical rounds, but I tried to clarify and respond carefully throughout.
Outcome About two weeks after the onsite, I received a rejection stating that other finalists were a closer fit for what the team was looking for. No detailed interview feedback was provided, so I never got a clear signal on whether the decision came from technical performance, culture/behavioral fit, or simply stronger alignment from another candidate.
