I applied online. I interviewed at Compass Lexecon in Nov 2014
Interview
I sent CV and cover letter by email. It took quite a long time for them to get back to me, because they schedule all of their interviews in certain weeks I think. I did the first step which was an hour of GRE like assessment and a short 15 minutes interview. Overall it was alright although I did not qualify for the next round. The quantitative assessment is not easy because there's really little time. No problems for the rest.
