Throughout the interview the employer will be examining you to determine if you possess a number of traits without ever asking you directly about them. You should stress these qualities in everything that you say and do - your body language, your tone of voice, your word choice, as well as what you are actually saying.
Poise and Confidence
Look the interviewer in the eye, smile, sit up straight, and avoid nervous habits and speech utterances (such as "er," "uh," etc.). Be careful though; there is a fine line between appearing confident and appearing egotistical.
Maturity
Show maturity by being on time, dressing appropriately, and being courteous and respectful with everyone that you meet. If you show clear thinking in your responses, as well as good judgment, this will also demonstrate maturity. Furthermore, in establishing this quality you should give answers and examples which emphasize that you are dependable, flexible, and have a strong work ethic.
Sociability
If you are friendly, courteous, and willing to chat with the interviewer, as well as any other employee that you meet, then your sociability will be apparent. The way that you talk about other people and your interactions with them will demonstrate whether you like people or not, and how well you will do in a social work environment.
Technical Capability
You should show an aptitude in the skills needed for the job. This means that you should be able to talk about technical details, in technical language or terms, relating to the job.
Creativity/Resourcefulness
Give examples of situations encountered in past work, relevant social settings, or anything else that will show that you can think quickly and creatively, and demonstrate your resourcefulness. However, don't overdo it, otherwise the overall effect of your examples will be lessened.
Enthusiasm
Lean forward when you are particularly interested in a point and vary the tone and volume of your voice to express yourself and to show enthusiasm. You want the interviewer to know that you are interested in the position and eager to work for him/her.
