It depends on the project you are on, and what your position is. I was in software, so 45-50 hour weeks were not unheard of, or days going beyond 8 hours - especially during a release. An entry-level position may only work 8 hours, but even then, 8+ is encouraged, and will get you noticed by management.

Eight hours was the standard. The client would not authorize overtime.
