Introductory call and followed by Design, Engineering Manager and People Management discussion. First 2 round was good, mostly they were asking questions on their business use case and design. Interviewer who took 3rd round didn't have any personal connect neither interested in discussion. During discussion started flipping the phone message, then received message in his office messenger which I could hear notification sound. Post started to check email and asked to write development process for Treebo CM business use, meantime he stepped out. When he came back was not interested to see what I have written. Too much, shell bound not interested to hear what candidate has done before neither interested to understand there are different process to develop product. Define the problem statement, don't be specific to the answer you need - be open to listen for different approach & process. Every company has their own process, hierarchy structure and procedure followed. Please respect the candidate and have personal connect, as it Win - Win for both.
