1 and 2 aren’t really big issues in my team. The biggest challenge at FB is that noone ever really disconnects. Constant posts, diff review requests, mesenger messages and work quickly trickles into your home. I’m on the lighter side but I would say for my team and around the averages are 60-70 hours a week. I’ve yet to see a weekend go by without many posts and diffs.
It is, but it’s a pain; I do a little email checking and replying even when I’m on vacation. Not because I’m expected to, but for my own sanity when I’m back. If I ever do take parental leave, I’ll make sure to delegate everything so nothing important comes my way
One major issue that contributes to bad WLB at Facebook is the traffic around normal business hours. You’ll burn crazy hours trying to get to and from of the campus at a decent hour. You can either arrive early:stay late and get a few more hours of work in or spend the time sitting in traffic.
