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?
As an engineer who is well off with a wife and a dog and a house, it was pretty much:
The best thing about engineering, as proved out by both my wife and myself, is that you can get just about any job even tangentially related to your degree so long as you have the right work ethic, strong enough people skills, and you can pick up whatever skills you need on the job.
If we ever got bored or didn’t like the company (which has happened to my wife twice now), you can just switch companies or in my case switch roles in the (multinational) company and be doing something entirely new until you find what really clicks, be that company or role or both.
