Feel free to be economic with the truth by using aliases for organizations and products wherever it protects your privacy or your contracts. I’m mainly interested to hear about your unique experience.
Example follow-up questions: What was most rewarding, what was not? What was not a great use of your time but maybe still a learning experience? What were you interested when you were younger (for hobbies or otherwise) that may have helped guide you?
Other thing about an engineering degree is, if it’s a good school, it’ll teach you as much about how to go about figuring things out as the specific topics themselves. Not even field-specific technical stuff, but “Here’s my goals, how do I figure how to get to them?” or “I don’t understand this; what is my strategy for acquiring more information about it?”
