real advice for an interview

i think buddy just forgot a bit about to behave for real, so i guess i feel a need to remind him for his own sake:
1) be polite and respectful, as all persons are deserving of respect
2) try to the best of your abilities to answer any questions put to you with due respect and politness
3) be polite should your thoat dry up and out
4) should the interview ask you the same question more than once, tactfully tell them so, taking into account that they might be embarrassed, a feeling no one enjoys
5) remember, you need this job, not them, and if you dont need this job what are you doing there - wasting their time, which is not polite nor respectful
6) enjoy yourself, get to know your interviewer, you never know, maybe you can learn something from them, or teach them something, thus leading to your mutual benefit
