Bhushan's response is highly detailed, explaining the steps involved in a complex data pipeline from polling to pushing data to Elasticsearch. He discusses the use of AWS ECS, Lambda, Kinesis, DynamoDB, and touches on error handling with DLQ. However, the response could be more organized and focused on scalability and maintainability, which were key points of the question. Bhushan could improve by clearly outlining how the pipeline was designed to handle scale and by discussing specific practices or patterns used to ensure maintainability, as seen in the benchmark response.
