Pros
Flowserve is a large corporation that has the feel of many smaller companies making up a whole. There's no way to describe how it works other than as a number of smaller siloed facilities that are all part of Flowserve. The benefit to this is that it's easy to be a big fish in a small pond, however, it can be quite easy to be relegated to a backward facility and have very little room for advancement. It is imperative to hook into an appropriate social network at the company in order to meet the right people and prepare for advancement.
Cons
There are some downsides at working here, as well - it is very easy to fall through the cracks and not have the ability to move into a new position. Most of the facilities are located in very remote, third or fourth tier cities (think Cookeville, TN, Sulphur Springs, TX, and so on), and just are not placed many people who are not from the area want to work.
