A similar thing happened to me. A Google HR staffer sent me an unsolicited offer for a job at YouTube. I accepted, and... A week later I sent an email asking "how long is the usual turn-around time on this?" Google's HR person said she would let me know by the end of the day, and that was that last I ever heard from her. All further communications were black-holed. I suppose I was unusually lucky to get that last message.
