How you come is across to an interviewer is one of the most important factors in an interview. Almost unfairly, the decision as to whether you are the right candidate, will be made in the matter of the first couple of minutes. Many of the questions about you and how you will be regarded by a patient will be answered subconsciously by the interviewer before a significant amount of time has passed in the interview Every candidate wants to avoid the appearance of being nervous and lacking confidence in the conversation, but in the quest for confidence, some candidates find something which looks much more like arrogance. This is truly something to be avoided, because once the interviewer has decided you are arrogant or smug, it will be almost impossible to recover your neutral position, where you were being judged on your merits alone.
