The process took 2 days. I interviewed at Citadel (Chicago, IL) in Feb 2009
Interview
Be prepared to answer a large series of puzzles, math questions, and programming/algorithms questions, along with your past experiences or knowledge of the field. The interview consisted of several brain teasers, a practical programming question, an involved optimization problem, and several trading/research questions. The employees that questioned me were very bright and courteous, but demanding.

Question 1
You are given an array of integers, A1, A2, ..., An, including negatives and positives, and another integer S. Now we need to find three different integers in the array, whose sum is closest to the given integer S. If there exists more than one solution, any of them is ok. Is there an algorithm to find the three integers in O(n^2) time?

Interview
two phone screens. some interviewers were nice and others were more strict, lots of interesting math and research discussed. got asked a flurry of technicals, ramping up in difficulty each time, and even some open ended questions where they explicitly said there is no interview-tractable solution and just wanted to hear my ideas for an approach

Interview
HR phone call, tech phone call, then on site visit.
No food or breaks provided, pretty exhausting by the end when you meet with the manager who I would never speak highly about.
