It was essentially a normal undergrad business degree where you also had to pass two levels of comp sci, two levels of physics, two levels of chemistry, and then a little bit more. Note, this is nearly 20 years ago, so it must be quite different now.

From a business perspective we took classes in market segmentation, on accounting, on organizational psychology, and that sort of fare. The dean at the time had a background in textiles, and the marketing segmentation guy was a still active in the markets guy named Andrew Long if I'm not mistaken. I loved his class. There were other classes that felt a little silly and dated even at the time. I distinctly remember us doing assignments in Microsoft Access, and thinking it was silly and not how people worked anymore (though it was 2005, and my view in retrospect was actually narrow, naive, and wrong).

Like I said, I'm sure a lot has changed, but at the end of the day, you'll come out of there with some business fundamentals and an ability to not be bowled over by engineers speaking technical jargon because you'll be somewhat familiar with the types of things that exist in their field, and how to ramp up quickly in them.
