If you are properly prepared for each conversation, you will reinforce all the positive impressions. Be confident, yet not cocky. Personal appearance does count. Plan to arrive early for your interview. Review the job description, industry trends and your notes about the employer prior to the interview.
All interviews fit a general pattern.
The typical interview will last 30 minutes, although some may be longer. As you can see, there is not a lot of time to state your case. The employer may try to do most of the talking. When you do respond to questions or ask your own, your statements should be concise and organized without being too brief. The typical interview starts before you even get into the inner sanctum.
