Build the UI and tooling layer that accelerates model development across Netflix's AI Platform

Netflix's Model Development and Management team builds the interface layer of the AI Platform — the tooling that lets ML researchers, engineers, and data scientists move faster through model creation, evaluation, experimentation, and deployment. This is a platform/developer-tools engineering role, not a modeling role: you're building SDKs and internal tooling for other builders, working alongside applied scientists across many Netflix teams.

Google L3 software engineer interview: phone screen, four coding rounds, and the Googleyness round

A candidate with two years of experience went from recruiter outreach to offer over about four months. The onsite was four 45-minute coding rounds — three of them featuring binary trees — and one round turned into a 25-minute chain of follow-ups about approximating an optimal solution at scale.

Google L5 software engineer interview: phone screening, three onsite rounds, system design, and a late rejection

A candidate interviewing for an L5 role went through a phone screening, three onsite coding rounds, a mobile system design round, and a Googleyness and Leadership round. Two of the four technical rounds went poorly by the candidate's own assessment, and after roughly two months of silence the recruiter reported that the role had been closed.
