Common Errors to Avoid

• Lack of preparation. If you have not done your homework or taken the time to groom yourself and get ready for the interview, then you will create a bad first impression that will be virtually impossible to overcome. 
• Arrogance or lack of confidence. Either of these extremes can be detrimental to your performance in an interview. You should find a balance between feeling confident about yourself and appearing egotistical.
• Unprofessional attitude. Be respectful and positive to everyone that you encounter and when talking about others. Bad mouthing previous employers or co-workers is a mistake and can be interpreted to mean that you are not easy to get along with.
• Poor communication skills. Not only is the capacity to respond in a coherent, organized manner crucial to your success in an interview, but just as important is your active listening ability. This means that you must listen carefully to the interviewer and ask questions when you are not sure that you understand.
• Answering questions with a simple yes or no. Always explain and illustrate your answers. You control what information the interviewer leaves with.
• Divulging personal information. It is illegal for the interviewer to ask certain personal  questions because they could provide a basis for unlawful discrimination. If you volunteer the information then you risk discrimination. For more information about illegal questions, see Questions They Should Not Ask.
• Bringing up money too early. If possible, wait until the interviewer brings it up. Never ask about money in the first interview.
