After my PhD in EE, when I started my graduate work in Linguistics I had quite a shock to see how different they thought and argued (and then I took a course in the philosophy of department,
that's a different story altogether).
My advice would be: Try to get the most out of meeting with them. It's easy to look down on the "soft sciences", but you'll be surprised at the insights you may learn. You should not use jargon, even if it sounds mundane to you, they won't understand it and think you're doing it deliberately to look clever.
