Walmart Software Engineer interview questions

I just had a initial phone screen. The HR person called me but he had set of questions to ask me...I answered 2 questions wrong...which were pretty basic....my bad !! But what pissed me off was, the interviewer was expecting exactly same answers as he had...which was silly....coz when he asked a conceptual kind of ques, you can frame it in ur own way, though the underlying basis would be same.......at the end of the interview, he went on to say that they hire only bright & excellent ppl..which was very rude.......walmart ppl indeed have very low standard communication skills....... sry...this is meant to only technical division ppl.....or specifically to HR of that division...
