I applied through a recruiter. The process took 1 week. I interviewed at Citadel in Apr 2010
Interview
Professional and forthright. Initial interview was phone screen with HR which provided good overview of company but few details about position. Hiring manager interview was by phone. Interviewer was very well versed in subject matter and asked clear questions. Provided good information as to what it is like to work on his team.
