Ok, but where are you located? Where is "here" and who is "we're"?

Europe is not a single country but every EU nations has different labor laws and working hour contracts.

I’m in Sweden, so Scandinavia. Every company I know has 40h work weeks. Lunch break is not included so if you start working at 8, take a 1 hour lunch break around 12, then you can log off at 17.

The normal (office) working hours here are 37.5 hours per week, excluding lunch break, which is usually 30 minutes. That breaks down to 7.5 hours of work + 30 minutes of lunch break, meaning you get in at 8am and leave at 4pm.

Last gig I had in Germany: it was 40h/week. I never seen a 36h/week schedule in France either... (I'm talking about standard software engineer positions).

In France base is 35h/week, 37/39 are frequent with the extra 2-4h hours then available 1:1 as extra vacation time ( RTT, you get hours on top of 35 worked over the year / 7 ( standard work day) of them over the year).

I'm currently on 35, might move to 37 ( majority at my company).

AFAIK only France has a 35hrs week (7h/day), most of the other countries has 40hrs week.

If we are counting actual working hours, it is also 7 hours a day in Poland. (8hr/day inclusive of 30 minutes lunch plus cumulative 30 minute break from staring at a screen).
