1. Self-Confidence
   Be confident of what you know and how you work, explain your benefits.
   
   
2. Experience
   Be prepared to articulate your experience and training.  Anticipate the questions the interview is likely to ask.  A lot of good workers have a hard time with this one, so be sure and practice speaking out loud, with someone who can play the role of the interviewer.
   
   
3. Compatibility
   The hiring employer is the only one who can answer the question of how well you match the needs of the job.  It is best to present yourself as honestly as possible.  If you try to be what you think they want, get the job, and it's the wrong match, both parties will be miserable.  It would turn out being worse than a rejection.
   
   
4. Reality
   Failure can be a growth experience.  It makes us understand what we have and makes us evaluate our professional goals.
   
   
5. Learning
   The entire job search and interview process is a learning experience.  Show willingness to learn new skills and any attempt you make to further your knowledge.
   
   
6. Be on time
   
   
7. Stay flexible
   Don't take the attitude "it's not my job".  Learn everything someone wants to teach you and try your best to succeed each time.  Keep an open mind.
