Pros
Most interns worked 3x a week which was great (since its unpaid), staff was friendly and welcoming, office was great (right near bryant park- awesome in the summer), events hosted are very cool and a lot of opportunities for networking, intern lunch with president and chairman is a great initiative, if intern takes initiative (reaches out to fellows for research work, makes connections, talks to permanent staff, pitch blog ideas to journal) they can make a difference at WPI, stay active and learn a lot. plus it looks great on a resume!
Cons
Unfortunately if intern does not seek out these work activities or opportunities they are not really given to you consistently at WPI, staff seems overworked and is not great at delegating their tasks (which can mean a LOT of downtime at work, boring, etc.), WPI hires a lot of interns (who primarily only interface with each other) in the summer so its easy to get lost in the shuffle or forgotten if you do not make the connections, no office intro at start of internship (a little strange not being shown around or anything), should plan more get-to-know-you intern activities or just generally make the interns feel a little more integrated into staff
