I applied through a recruiter. The process took 2 weeks. I interviewed at Jane Street (New York, NY) in Apr 2014
Interview
Contacted by recruiter, was sent a series of excel tests. Phone screening, followed by face to face. Face to face involved tests and multiple interviews with personnel. Plan on being there all day if you do well on the tests.
