The process took 1 week. I interviewed at Nunwood in Apr 2011
Interview
First round was a phone interview. Just your typical "tell me about yourself" stuff with an HR rep. Two days later I got called back for a 2nd round which was a presentation. They e-mailed me a somewhat large data set to play around with. I was to come up with a solution to a hypothetical situation based on the data.

Question 1
The 2nd round interview was purely about applying a multitude of statistical tests.
