I believe its 100 hours a week, which frankly sounds absurd.
My comment is not ignoring either of your points since:
1. I state the salary will go up.
2. The point of my comment was to realize that making 125K is not much if you are working 100hr/week and have no time to enjoy it, thus a high salary might seem great but looking at it on an hourly basis can be useful etc.
In life, generally you can have more money or more time, rarely can you have both. I would rather have more time personally.
