Confluent Interview Questions

Confluent's Data Infrastructure Engineer new-grad loop in 2026 is for engineers working on the streaming engine itself — Kafka core, Kafka Streams, ksqlDB, Confluent Cloud control plane. The loop is the most distributed-systems-heavy in the company: a coding screen, a deep distributed-systems round, a system-design round, and a behavioral. Bar emphasizes consensus protocols, replication invariants, storage internals, and the ability to reason about correctness under failure.

Confluent's new-grad SWE loop in 2026 is a CoderPad screen, a technical phone round, and a 4-round virtual onsite covering coding, distributed-systems fundamentals, a system-design round, and a behavioral on Confluent's values. As the company founded by the creators of Apache Kafka, Confluent's bar emphasizes deep systems thinking even at new-grad level — replication, partitioning, consensus, log compaction. Kafka domain knowledge is fair game and expected for product-team roles.

Confluent's SWE intern loop in 2026 is a CoderPad screen and a 3-round virtual onsite with coding, light system thinking, and behavioral. The intern bar is calibrated for undergrads but still touches distributed-systems concepts. Conversion to full-time return offers is a major hiring path.
