In my anecdotal experience, arriving at work around 7 or earlier and leaving before 16:00 is absolutely not a problem. Arriving around 10 is also possible for those who prefer starting late. People try to group the important meetings in the middle of the day to accommodate everyone. Working overtime when needed happens but those hours can be grouped to take a few days off. I don't know if it is generalized but it's the case in the two companies I worked for in Germany.
