I applied online. The process took 2 weeks. I interviewed at Bloomberg (New York, NY) in Oct 2014
Interview
The interviewer was pretty straight forward. We went over my resume, my current interests and goals. We then went over the technical questions using Hacker rank's Code-pair. The interview questions weren't too hard. The interviewer was pretty helpful though, giving away some hints. Being a freshman, I was underprepared.
