I applied through college or university. The process took 2 weeks. I interviewed at Metropolitan Transportation Authority (New York, NY) in Jan 2015
Interview
It's a round table interview with the whole department. Questions are really nice. After my interview, I received the intern offer in two weeks. The whole process lasts about 1 hour, I just kept talking about my experience after they generally introduced themselves and their department.
