Dan Lyons, a former tech journalist who wrote a funny blog years ago called "Fake Steve Jobs" and wrote one of the best episodes of HBO's Silicon Valley ("White Hat/Black Hat") gave a funny 20-minute talk about his horrible experience in a start-up.
From YouTube description:
When he lost his job at Newsweek, Lyons – who had long reported on Silicon Valley companies – accepted an offer from HubSpot, a red-hot Boston startup, as a "marketing fellow". Watch the talk to learn what happened next.
