Confluent interview questions to expect.
These are the kinds of questions candidates commonly face in Confluent and similar interviews. Prepare a specific story for each, ideally with the STAR method.
Confluent is built around Apache Kafka and event streaming, so tell me how you would design a system to process high volume real time data streams reliably.
Tell me about a time you worked with streaming data, message queues, or distributed logs. What challenges came up?
Walk me through how you would reason about data consistency and delivery guarantees in a distributed system.
Describe a time you diagnosed a difficult performance or scaling issue in a data intensive system.
Tell me about a project where you contributed to or built on open source technology.
