Their CIO is a vicious, vindictive and rude.
Zero communication.
His competence can be gauged by, they didn’t have a QA environment and a QA database for testing. When I joined in a raised this concern and explained the founders how big and dumb move was this. Since then the CIO went against me and tried his level best to remove me. At last he was successful after a year when the new management came in who had no idea what his intentions were while giving reviews about resources.
