Avoid talking negative things about your last job or boss in the interview. Talking badly about the previous employer reflects badly on your attitude. Make sure that you show your enthusiasm for the position you are being interviewed for and that you are really interested in working here. If you stay dull, the employer will take it as lack of interest and eliminate you for being a misfit.

It is important to make a list of your strengths and achievements in the last positions you have held. They give you the confidence and help you in demonstrating yourself as a strong contender for the position.
