They provided a lot of hands on opportunities to the interns to learn about their chosen field. We also got to do a few field trips where we saw the maintenance yard as well as talk to the elevator/escalator staff. Amelia (the person that runs the internship program) was so helpful and encouraging. There is a really positive work environment at BART and I really enjoyed working with my boss and the other people on the Civil Engineering team.
Cons
The only thing I would say is the final presentation prep kind of took a lot of time away from the work I was doing for my team.
