Yesterday I received a letter from a Facebook recruiter that was quite nice and professional, but I am clearly not on the market for a new job right now. I responded with a rejection letter:
Thanks for the connection request. While I was impressed with your credentials, at this time I do not see an opportunity for me to leave my company to consider a position with Facebook. Best of luck with your future endeavors.
I’m pretty much screwed now if the startup fails and I end up at Facebook’s door with my hat in hand.
