U know what? house, Let's not harp much on the blunder the guy has made but rather scan in between the experience. I think the guy has made a point within the context of his/her intention. My own understanding about that is; Whenever you are expected to ask an interviewer any question, it is advisable to ask questions like WILL YOU HIRE ME? and so forth. And another question like ASK YOUR SELF ANY QUESTION. Then the response the bearer provided was, WHAT IS MY NAME? OR WHAT AM I WEARING? Ofcouse you cant be stupid enough to ask your self a tough question that you wouldnt be able to answer. Left to me, I will do the same thing. So I think the bearer has offered something here.
Therefore, lets not always be on the watch out for errrors our colleagues have made but rather learn from it and if possible look for a more matured way of correcting ourselves.
