HR girl sent a generic email with the job description and benefits of the company but forgot to set it as BCC.

Not 3 minutes passed that all the 73 recipients of the mail (me inlcuded) start replying to all making jokes about it, ranting about HR in general.

An hour later we created a Facebook page called "not-BCC guys" where we keep us posted about opening positions in our companies to bypass future HR hunting interactions.
