Operations Analyst

I applied online through through my school's website. Shortly after, the company sent me a skills test. It wasn't difficult, and I finished with time to spare.
I then received an on-campus interview, which was a basic case study. The case was very straightforward. Identify areas that could be changed to reduce costs or increase revenue, followed by profit calculations. The assumptions for the case were then changed, and I was asked to recalculate profits.

I was invited back for the superday in Plano. This was similar to the first, but consisted of 4 cases and 1 fit interview. The cases were much more difficult than the first round, but very doable if you have had some quantitative course work. The interview consisted of some fairly complex graphs, which I think is where I fell short. My largest piece of advice is to not assume that the graphing portion will be simple to plot.
