This would be a great opportunity for a bachelor or master in economics, but not a Ph.D. as I outline below. Please read this in its entirety as my negative comments may not be applicable to most situations and this is a good company for many career paths.
I applied online and was contacted very quickly to set up an interview. The posting indicated that a Ph.D. in a relevant field was desired and I am an economics Ph.D. During the interview, it became pretty clear that the work I would be doing was not Ph.D.-level work. The interviewer seemed to think that a Ph.D. was just a sharper, more in-depth bachelor's or master's degree, which any Ph.D. knows is not the case. A Ph.D. is fundamentally different and is about producing knowledge, not absorbing and applying it.
I withdrew after a salary conversation convinced me that I would not be doing Ph.D.-level work at CEB. Had I wanted to proceed, the interviewer seemed positive enough about my abilities that would not be surprised to receive an offer.
There may be good opportunities for economics Ph.D.'s here, but this evidently was not one of them. It could be just that the interviewer did not know what a Ph.D. is all about. For someone with a bachelor's or master's degree, this really would be a great place to work, but if you have a Ph.D. and want to use it, this is certainly not the place, unless my situation was specific to this interviewer.
