R+L Carriers Database Administrator interview questions

Initial 2 phone interviews with Hiring manager and Database manager went well. Third interview was with Tech officers. Was invited to a "WebEx" conference and logged into the session. No courtesy to start the video on their side. Answered some technical questions, then was asked how I knew what I knew. Tech Officers would not take experience (14+) years as an answer, and wanted me to cite specific sources. Tech officer became very argumentative, and I quickly lost interest in the position.
