@CollegeCrazy While Wharton definitely has a strOng presence it also definitely does not overshadow everything. SEAS students are very successful in landing Silicon Valley jobs both as engineers and in the business sections of top tech companies. In fact there are also quite a few Wharton kids nowadays who choose to go into tech finance, product management in silicon valley rather than the traditional ibanking wall street route. A look at Penn SEAS career statistics here will convince you. Also Penn SEAS students are very successful in getting ibanking jobs. http://www.vpul.upenn.edu/careerservices/reports.php
In general I think the strength of Penn SEAS is that you get a very rigorous engineering education but at the same time a very well-rounded one because the curriculum is designed that way so you can take quite a few courses outside of SEAS too, and also Penn is strong across the board in many fields. In my opinion it is important that ones undergraduate expeerience is not one-sided/limited.
A cool thing that Penn SEAS organizes twice a year is the Penn Apps which is arguably the biggest college hackathon in the country and many major tech firms sponsor it and it is an great way to make connectiions, get experience etc. Prices are first round interviews with the likes of Facebook, Apple etc and many SEAS students are actively involved in organizing it as well as participating. Also Penn has amazing robotics, nanotech departments where computer science people can really apply their skills on top of many CS-oriented research position available at Wharton and the Med School amongst many others.
