The process took 1 day. I interviewed at Nomura (City of London, England) in Nov 2011
Interview
was called to office for a 2 hour interview with 2 guys, both very friendly. the first one is more computer scientists and asked a lot about programming and problem solving. The other one is kind of mathematician and focused on maths side, asking a lot of brainteasers which are not hard though.
