Lessons from Mark Zuckerberg, Founder and CEO of Facebook: http://blog.facebook.com/blog.php?post=2208562130 This was a big mistake on our part, and I'm sorry for it. But apologizing isn't enough. I wanted to make sure we did something about it, and quickly. So we have been coding nonstop for two days to get you better privacy controls. Lessons from Yishan Wong, Director of Engineering at Facebook: http://www.quora.com/What-are-some-good-questions-to-ask-yourself-to-determine-if-you-are-ready-to-join-a-startup Working at a startup doesn't necessarily mean long hours, but it does mean that it's not the hours that count, it's the results. If you need to work 80 hours to get something done by next week, you will need to do it because otherwise the startup might die - in a large company, this might just result in some mild consequences. Startup life tends to go in bursts. You should be comfortable with this. Had Mark Zuckerberg left at 5pm in the middle of the news feed crunch, the company probably would have died before it was able to pay Sheryl Sandberg so much money to work 40 hours a week. Instead they coded 48 hours straight.
