Congrats! Both great schools. I will echo the pure beauty of the Lehigh campus, one of the prettiest I’ve seen.
For your purposes, the IBE program turns Lehigh into a Lehigh + if you will (and Lehigh regular is just great). Having that dual degree of engineering and business is very appealing if you aspire to a career beyond the fully technical side. Knowing how things work, learning how to solve problems (really the core to any engineering discipline), and then applying them to the business world in a practical way is quite compelling. Their IBE program is highly selective and unusual. And they attract lots of marquee employers who seek a kid with that blend of skills.
Anecdotal but makes the point. Have a buddy who’s son just graduated and was hired by one of the top and most influential PE shops in the world. One that typically doesn’t hire out of UG. It’s a very unusual program with some intriguing outcomes (beyond salary). Places really well in NYC if that’s of interest.
