I applied through my school's Career Center website and was given an interview slot for an on campus interview. The interview consisted of a brief case interview that had to do with gym access for employees and its break even point when costs where compared to savings (productivity increases, health care savings, etc). The case required basic algebra including setting up a system of equations based on the information in the case and solving it for the two possible break even points. Basic graphing skills were also required. Overall it wasn't a terribly difficult case but it was easy to get bogged down in some of the superfluous details.
