The process took 1 day. I interviewed at SMB Capital (New York, NY) in Aug 2010
Interview
Pretty basic interview with behavioral taste. Interest in trading was probed intensely, but no brain teasers or anything like you would expect at a bank. There was an indirect attempt to find out my age by asking for my college graduation date, which I did not appreciate. Two interviewers were cordial and pleasant, no stress strategy, work culture appeared fairly informal.
