I applied online. The process took 3 days. I interviewed at ISO Developers (Boston, MA) in Dec 2015
Interview
Very nice, Talked to different workers and was asked many questions about my experience and some personal traits. Liked the atmosphere a lot, was in a very nice room with couches so felt more relaxed and performed better than expected, cause wasn't stressed too much. Got a full time offer instead of unpaid internship position.
