The panel will not be able to accept for evaluation any additional materials brought to the interview. You must articulate whatever it is you want the panel to know about your qualifications for the position. Because the interview time is generally limited to approximately 20 minutes, candidates should try to keep their answers to the questions as concise and as well organized as possible, but at the same time, you need to provide the panel with enough information about your qualifications so they can accurately rate you. Remember that, if you are invited to an interview, you will be asked to discuss your qualifying background during the interview, so be sure you have taken the time to arrange your thoughts and know exactly what you are going to say. Also, remember to relate your background to the job for which you are applying.
Personal appearance needs to be considered.
While it is not a factor that is measured in the testing process, it is important to present oneself in a professional manner in an oral testing situation, and dressing appropriately is a must. Casual attire, such as jeans or sweatsuits, is not considered professional attire for an oral interview. At the conclusion of an interview, the panel will ask if there's anything a candidate wishes to add. This is an opportunity to make a closing statement briefly summarizing your qualifications or reinforcing your interest in the position. If there is some particular factor that qualifies you for the job but was not covered in the interview, this is the time to mention it to the panel.
