I'm not quite sure I follow.. are you suggesting that not wearing a tie would mean "removal from the process", even today? I've never worn a tie to a programming interview and generally it seems most experienced developers don't, at least in on the west coast of the US
Once upon a time, not wearing a tie would have been unacceptable in a job interview. This is no longer the case and the world has not collapsed into a heap of smouldering cinders. I believe the point was that a few spelling mistakes should not disqualify someone from being interviewed for a programming job.
