Ubisoft - just(disclaimer) keep in mind that we have studios in (almost) every European country and all of them can approach this differently. Here in UK the policy is what I explained above.
I'm not 100% sure about Ubisoft, but I think Gameloft is part of the same group. At least in Romania, Gameloft definitely does not have a good reputation concerning overtime and such.
"reputation" is a hard thing to assess. In a company with 20k employees, there are goign to be teams and offices that differentiate from the norm, in both good ways and bad ways.
Clearly depends of where you work, and what you do Inside Ubisoft. My rule of thumb is that the closer you are to the game itself (Dev, gameplay designers, sound designers...) the more you will crunch and the less you get paid. As if the labor was a perk in itself.
Again, only talking about my own experience - I'm a programmer myself and I don't crunch, and no one in any other team that I know does. Programmers also tend to be most well compensated out of everyone(in my experience).
