My hours are often long, say >12 hours per day. I typically do not do work on the weekend.
Hours are dependent on what kind of engagement you are on. They can get long and grueling, however you are always rewarded at the end of difficult engagements in the form of entertaining nights out! There has been a strong push from leadership to improve work/life balance the past year.
Very varied depends on project. I have had days where I finished early in the afternoon and days where I finished much, much later
Most projects I work ~12 hour days. When between projects we are able to work from home
