From when did working 30+ additional extra hours just became a sign of being merely committed? The way I see these are just mind games played to extract tons of work for free.
I see this pretty standard these days. The Google 20% time policy is a standard in many companies to get free innovation out, while your grinding your bones to dust(sold to you as 'chasing your passion' , 'developers like to code during late night and weekends', 'world changing problems' etc) working whole nights to get some thing done, a VP some where is sleeping through his job. What happens at the end of it is the VP gets a fat bonus and a promotion for 'driving the innovation' while you are at the very best known to be just 'committed' and given a certification, which isn't even worth the paper its printed on.
Almost any time you hear some senior guy glorifying long working hours, demanding free innovation and depicting heroic contribution as just doing bare minimum job. Know one thing for sure, this guy is going to leech you till the last drop of blood in your body.
