Remember to be authentic in your response. While this is largely an opinion-based question, companies often reach out to former co-workers and bosses to validate the information provided in an interview even if you have not provided their names as a reference.

"My current boss would most likely describe me as eager, curious, and trustworthy. I am always popping by her office to ask if there is anything more I can do, and ask questions as new situations arise. She's really great about breaking complex business scenarios down for me because she knows I want to be a project manager. She also shares information with me that is confidential from time to time and knows I am able to use the information to learn how to be a good manager, and will not use it for office gossip."
