You can never get into any kind of detail with people from a different career path.
Like, "I'm a software engineer" is the most people understand. If I say "I write tests for the GPU factory to improve semiconductor yield and screen parts" then launch into something about product binning, there's only 1% of people who'll be interested. The typical marketing person or government bureaucrat won't care.
Meanwhile "how do you know x" launches into a story about 'x', a person we both know and care about. Then we can swap stories.
What? I get so much joy out of learning the details of careers of people in different industries than me. I had an hourlong conversation with someone the other day who is in the high-end rug business…where he sources from, how he deals with difficult clientele, how he gets new leads, what it’s like visiting the remote villages where the rugs are made, etc. And another one with a hedge fund quant, and a separate one with a professional dancer. These are some of my favorite conversations to have with people.
I love talking to people about their work, especially if it's a field I know nothing about. People spend eight hours a day doing something, they have a lot of knowledge about it.
When it's a job that's opaque to me, I like asking "What's a typical day for you like at work?"
