Simple process, applied online , got call from HR to setup 1 hr call with hiring manager , asked some design question. Nothing hard. Round: 1. Tech call as leet code question. 2. Tech call, all question on Flink Data Streaming. 3. Tech Call , System Design & deployment DevOps 4. Again call with same hiring manager, shcduled for 45min. done in 30 min. Overall not a good exp. everything was fine. in las call itself hiring manager confirm it but later HR told you are not received the positive feedback which was surprise for me. waste of time.
