I think it depends on the division you work in. Some guy working in the networks/infra team may get better work/life balance than someone else in the front-office development team. I work in the latter and I must say the hours do suck and you tend to be drained when you get back home after work. But I believe that if you have a strong will and good work ethics you can still manage to work on side projects in the evenings and week-ends. Hard but feasible.
