This http://www.WorkTree.com article by Nathan Newberger gives you some common sense advice and tips on avoiding potential interview disasters.
There are definitely things that you can do to avoid minor mishaps which could ultimately blow an interview. Become familiar with these 7 potential interview disasters so you can prevent them from obstructing your path to that ideal job.
1. DON'T ARRIVE LATE Showing up late is both rude and inconsiderate. Is this first impression that you want to leave with a potential employer? Map out your route and try it out before interview. Plan on being at least half an hour early to your appointment. This will provide a buffer to protect against wrong turns, traffic jams and all other mishaps that may befall you. If you arrive early, you can use time to calm your nerves.
2. DON'T SAY THE WRONG NAME Many a nervous candidate has been known to accidentally call interviewer wrong name. In order to avoid this disconcerting faux pau, find out who you will be speaking to before interview. Memorize name(s). If this information is not available prior to meeting, then write personís name on your notepad as soon as you sit down for interview. If you do slip-up, do not make a huge fuss. Apologize quickly (and sincerely) and move on.
3. DON'T SAY THE WRONG THING Choose your words carefully. Avoid impulsive answers; first thing that pops into your head may not be best response. Remember, itís ok to pause if you need some time to think. Feel free to say "thatís a good question; let me take a moment to think about it." This demonstrates that you think before you speak. Is your everyday speech peppered with expletives or other potentially offensive phrases? If so, take care to avoid these during your meeting.
4. DON'T BECOME SPEECHLESS Interviews are stressful situations for even most qualified candidates. This tension can lead to candidates "freezing up" during meeting. Alleviate some of expected stress by practicing mock interview questions. Have a friend conduct simulated interviews. If possible, have him/her conduct interview in a variety of manners including reserved, rushed, and disinterested. This way you will be better prepared for whatever interview may bring.
