As with any consulting firm, there are high expectations which go with the level of responsibility you are granted. The focus on delivery means that there are times when excessively long hours are required - however in my view the culture of constant long hours is dying. There is an expectation that managers will plan projects on the basis that people work normal hours, and despite peaks and troughs in activity, if the hours are consistently long then it reflects badly on the manager. There is also a lot of travel, sometimes to great places and sometimes to the middle of nowhere.
