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?
Got IT training during my time in the military that ended up opening the door to a network engineer position with a defense contractor after I got out.
I was a pretty poor engineer, but I was good at explaining technical details to non-technical people. The bosses liked this because they wanted constant updates on what was happening, the other engineers liked this because they didn’t want the bosses to bother them, and I liked it because going to sit in briefings got me out of doing real work, so I ended up in management.
