Design large-scale distributed data infrastructure on Netflix's Data Platform team
Prep for a Netflix L4 Distributed Systems Engineer role on the Data Platform org, which spans storage/movement infrastructure, the Data Mesh/Data Bridge movement platform, a managed key-value store on Cassandra, and developer-experience tooling. This mock is calibrated to the JD's own bar: 2+ years building large-scale distributed systems, RESTful services, and Java/OOP with multi-threading — a mid-level IC interview, not a staff-scope one.
