I saw a few posts from members who are going for job interviews seeking advice, here is the best I can offer: Start your interview with a SMILE.
To get you smiling here's what not to do (some info I found and edited over time):
Vice Presidents and personnel directors of the one hundred largest corporations were asked to describe their most unusual experience interviewing prospective employees.
* A job applicant challenged the interviewer to an arm wrestle.
* Interviewee wore a Walkman, explaining that she could listen to the interviewer and the music at the same time.
* Candidate fell and broke arm during interview.
* Candidate announced she hadn't had lunch and proceeded to eat a hamburger and french fries in the interviewers office.
* Candidate explained that her long-term goal was to replace the interviewer.
* Balding Candidate excused himself and returned to the office a few minutes later wearing a headpiece.
* Applicant said if he was hired he would demonstrate his loyalty by having the corporate logo tattooed on his forearm.
* Applicant interrupted interview to phone her therapist for advice on how to answer specific interview questions.
* Candidate brought large dog to interview.
* Applicant refused to sit down and insisted on being interviewed standing up.
* Candidate dozed off during interview.
The employers were also asked to list the "most unusual" questions that have been asked by job candidates.
* "What is it that you people do at this company?"
* "What is the company motto?"
* "Why aren't you in a more interesting business?"
* "Why do you want references?"
* "Do I have to dress for the next interview?"
* "I know this is off the subject, but will you marry me?"
* "Does your health insurance cover pets?"
* "Does your company have a policy regarding concealed weapons?"
