He did you a favor!  Thank goodness it was only two months!  How could anyone be expected to work that many hours?  This is clearly a violation of labor laws, not to mention abusive - yes, I said abusive.  Working for a CEO should bring a much higher salary, as well.  It sounds like no one will be able to thrive in that environment!  I'm surprised that you stuck it out that long!  Please know that it's not your fault.  You should get a gold star for effort next time around and your next employer will feel very lucky to have you, indeed!
