A few more pointers to keep in mind are:
- Never interrupt or finish a sentence for an interviewer. Even if they are the slowest talker or worst stutterer you have ever come across, be patient. Don't forget that they hold the admission ticket to what could be your perfect job.
- Don't fall into the habit of telling long endless stories to illustrate a point. Interviewers will give you a clue that this is what you are doing by interrupting you or asking you to keep your answers short.
- Never try to intimidate any interviewer. You may win the battle, but you will lose the war.
- Don't ever find yourself disagreeing with any interviewer. Nobody likes that and it leaves a bad impression, no matter how slight. Avoid getting bogged down in a pointless debate by trying to provide related topics of conversation that will allow everyone to move on.
- Don't ever be tempted to lie because when you are found out (and you will be found out eventually) the relationship will be damaged because they can not trust you to the same extent any more. If you are caught lying during the interview it is highly unlikely that you will be offered the position.
- Don't make any physical contact other than shaking hands. If they slap you on the back or nudge your elbow during a joke - don't touch back.
