Don’t worry we have those 80 hour weeks in software too. I can think of a few examples. For example with mobile App Store review time used to be kind of like that. You submitted your app waited a few business days and prayed there wasn’t an obscure rejection that lead to an appeal which could take even longer. Very stressful when you are cueing up a launch and press releases on a certain date. you had to make sure you were done a few weeks in advance to account for everything.
I don’t work much on apps anymore but I hear it’s somewhat better now.
Another big area is compliance, those processes can take forever.
