It's actually the opposite from my experience. It's very easy to get asked to work late (getting asked "hey, can you look at the build blocker?" towards the end of the day) compared to being asked to work early (barring having to acomodate any meetings with time zone differences).
It's just an anecdote, but I've never once been asked to work early in my software development career.
> ADDITIONAL REQUIREMENTS: Must be able to work extended hours and weekends as needed.
How often does this happen? Does management encourage employees to work reduced hours and take extended weekends to counter-balance the required crunch time?
That's not true at all from my experience, quite the opposite.
For example, in California the speed of traffic on the highway is quite often 80-85mph in a 65mph zone, and not enforced. That wouldn't fly in Germany on any road with a speed limit.
