Discuss Distributed-System Experience with Go, Java, Spark, and Elasticsearch

Describe your relevant project experience building distributed systems with Go, Java, Spark, or Elasticsearch. Explain the role of the technologies you actually used, the system's data flow, a technical decision you owned, and the result. ### Constraints Do not claim experience with a technology you have not used. If you lack direct experience with one listed technology, explain the closest relevant experience and what you would need to learn. Any example without personal experience must be labeled hypothetical. State scale and outcomes only when you can support them. ### Clarifying Questions - Is the interviewer most interested in online services, distributed data processing, or search? - Should the discussion focus on one project in depth or compare experience across projects? ```hint Connect the technology to its job Describe why a component existed and how data moved through it before listing libraries or product names. ``` ### What a Strong Answer Covers - Accurate personal ownership and relevant experience with the named technologies. - A concrete architecture and the responsibilities of its components. - A technical choice, operational consequences, and evidence of the outcome. ### Follow-up Questions - What was the hardest failure to reproduce across component boundaries? - Which technology choice would you reconsider for a smaller workload?
