The process took 1 day. I interviewed at Cornerstone Research (Los Angeles, CA) in Oct 2009
Interview
Interviewed 1:1 by two associates.30 min each. Each interview starts out with general q's: Why do you want to work for Cornerstone, etc. This is followed by a case study. The case study is based on an actual project on which the interviewer worked. The interviewer walks you through the case, e.g. You have the following sales data for Company X. It is suing its manufacturer, Company Y, over lost sales bc of defective parts it received from Company Y. How do you determine whether the decline in sales is related to Company Y's defunct parts?
