Work life balance? What's this? GB may state they offer this by "being flexible" but this really means, they'll let you run errands but you better be by your phone.
Vacation? Illness? Death in the family?
They do not care. You better be by your phone. They'll let you go, they'll just call your cell or not so subtly require you have wifi and your laptop.
The workload expectations are unrealistic. Then they'll ask if there is anything they can do, as though giving you 80 hours of work to be done in 40 is feasible.
They'll start nice and supportive, but then the mask will slip.
