Yes.<p>I left a startup that eventually exited prior to my first year. vesting.  The manager I had was one of those that was a smart guy, but didn&#x27;t know his limits and between checking in broken code, aggressively (to the point of insult) insisting people work insane hours, and pushing for outsourcing more and more to a firm that was incompetent, I had enough.  Being lead engineer and stuck with a launch that had no prep or IT people in place didn&#x27;t help.<p>My favorite two stories were:<p>1) Disappearing on a weekend (well before launch) for my wife&#x27;s birthday down to Big Sur.  I had told people, but apparently it didn&#x27;t register.  I was at work Monday and lectured despite a 70 hour week the week before.<p>2) Getting yelled had for whiffing and underhand toss of a pen to a colleague (and friend) of mine during a meeting where we went up to write what we were doing on the whiteboard.  Said manager thought I was annoyed and chewed me out.  I pointed out, I had just pulled an all nighter and was fucking beat.<p>When I walked, I told the management team straight up he was the reason I was leaving.<p>A colleague&#x2F;friend (he was the UI lead) had hoped to stick it out awhile, he lasted a month after I did.<p>I went through the frenzy of bubble one, had fun.  I&#x27;m usually pretty darn dedicated, but that startup showed me my breaking point and I&#x27;ve avoided such situations since.
