I think it got me an interview once, but nothing ever came of it. In retrospect one of the questions I was grilled on in the interview was based on a SO answer I had given; it was so long ago that I didn't remember the specific point the interviewer was looking for. I didn't discover the connection until something made me revisit the answer years later.
