The interviewer made it impossible to get back in touch to send the obligatory thank you card/e-mail. No business card, no e-mail nothing. Only gave one phone number that was for the entire HR department for the company. The interviewer also only asked one question. The opening question was the only question. In class you are taught to not give everything you have done away in the first question because there will be more and you do not want to bombard the interviewer with too much information. Apparently this interviewer wanted the opposite. The interviewer was also 3-5 minutes late.
