I started to get the sense that work-life balance would be a problem at this company when I noticed that the girl setting up my interviews was sending emails and meeting invitations at odd hours. I had been interviewing for a role at a Very Cool Tech Company, and the scheduler was sending me messages at 7:00 pm, 8:00 pm. There were subtle signals that the pressure to meet the expectations of the job would be large. And then, the kiss of death, the phrase that made the work-life balance question clear: "This is not a 40 hour a week position." It was clear that it would indeed be much more than that.
