Pros
OW is a professionally run organization that offers the opportunity to showcase skills and really grow in your role. The workplace varies based on the 5 subsidiaries that make up OW, but for the most part, it's what you would expect from a NY-based consultancy. Very flexible work arrangements, long hours, and overall, very intelligent, dedicated, and diligent people, from the bottom to the top of the organization.
Cons
Working at a consultancy, you are a slave to the ups and downs of the economy. Essentially a luxury more than a necessity, you have to worry about the ebbs and flows of industry. During good economic times, the business and workplace is thriving and filled with energy. During a downturn, job losses and downsizing are a harsh reality.
