Utilize a burn out model with their consultants - Associate Oliver Wyman Employee Review

Some Associate Partners / Partners utilize a burn-out model with their junior and mid-level consultants. It's not uncommon to work 20-hour days and 30-40 hour weekends. Looking back on the experience, the burn was absolutely unnecessary as it didn't add any value to the client but it was just how the company operated. As an example, after a long workday, an associate partner once asked for a powerpoint deck draft to be completed by midnight (something which should take a few days). Once that was sent, he asked for changes to be completed by 3AM. This was not an important, time-sensitive deck. It was something used as support which the client may or may not have paid attention to. Consultants typically only last a few years and then move on to something sustainable.
