It’s not impossible and not sustainable. A 12/5 or 10/6 is considered “normal” in my industry/company. It’s toxic af but a lot workplaces in the US bake in competition as either an incentive for compensation. Some teams have a mandatory oncall rotation that fits that schedule if not slightly more

The number of people replying anecdotally to this and other comments make me think it’s a lot more pervasive than I’d assumed. Young people in particular are being encouraged to work these kinds of hours to “get ahead” or “show initiative” in the hopes they don’t get laid off or overlooked for promotions

I personally work it and I cannot handle it. The second I’m home my brain is done, only have time to do some mild (unhealthy usually) mental decompression and sleep poorly lol
