Sorry to hear it didn't go well for you the last time. I know a bunch of people who passed the interview process only in a later try. I personally do 9-6, take my coffee breaks really seriously, sometimes to later work like reply to messages if I'm in the mood, and never (save for very very rare shitstorms) work on the weekend. Teams vary, I've seen plenty of 9-5ers that make it work (some of them on my team). As you already pointed out, I also think younger people tend to overwork, and people with kids tend to reprioritize and go for a 9-5 schedule. Since one gets to choose the team they join in Facebook (in contrast to being offered a job in a specific team) you get to choose a team that will fit your personality. This means you should pick a team not only based on their project, but also based on the people and the team's culture, and if you pick wrong, you can rather easily switch.
