My first 5 years at ACN (when one is an Analyst and a Consultant)average hours per week was about 60. But that was back in the days when we were paid overtime and thus it was the norm. Such hours still happen, but I doubt they are as common as they were previously. When deadlines were approaching or things slipped, add on another 20 hours, since weekend work would be required.Then next two years as a Manager, hours were a little less, but not by much, although the amount of travel dropped off quite significantly.Then I jumped ship to Capgemini, where there is a healthy work-life balance, given my role etc. the hours are a bit better, but when deadlines approach, proposals to be done etc. you can be hitting the 70's now and then. Average is about 50 hours.Effectively, consulting is not a 9-5 job. If anyone thinks otherwise, they are going to be in for a shock.
