It's not easy being one of the many job seekers out there and the job search is rough, so when you get an interview, it's extremely important that you do all of the right things and do your best to avoid doing things that are not going to make you look good during the interview. Remember in this economy we find ourselves in today an interview is scarce and extremely valuable and you don't want to ruin your opportunity and lose out on a job not because of your lack of skills but because you did something that turned the employer off.
Being called in for that interview means right off that there was something about your cover letter and resume that made you stand out amongst the crowd and something impressed the prospective employer enough that they want to meet you. Of course you are going to be nervous and excited at the same time but remember, don't let this excitement get you into hot water by letting it make you talk too much and slip and give out far more information you need to at this phase of the game.
Remember, even in today's world, first impressions stick. So make sure that you dress conservative and make sure that even the jewelry you wear is simple and does not show anything about your beliefs as a person. Just wear something neutral and simple that doesn't make a statement in any fashion. Avoid religious jewelry, not because it's wrong only because you never know how someone might feel. Although it is your right when on the job to be able to express your beliefs in this manner, during an interview just for your own sake try and avoid it.
Make sure that you bring an extra copies of your resume with you in case you are interviewed by more than one person and they expect you to provide them with them. This is part of showing that you are a prepared person, because after all they could make copies themselves. This also shows them that you are more than willing to share your qualifications with them.
If they ask about your different outside interests and hobbies it's OK to let them know about them but whatever you do, don't make the hobbies and interests appear as if they would interfere with your work and the time you spend at work. Don't make it appear that you will need time off for such things up front, even if they might sometime down the road, don't let them know that at the interview.
No matter how well the interview went or how bad you think it may have gone you should always, and this is stressed, always send the person that interviewed you a thank you letter. Thank them for taking the time and interest in them to interview you and let them know just how hard you will work for them and how committed you will be to their company should they decide to hire you. A follow up letter may be the key that helps them make their final decision and call you in for the job. Many people don't do this and often miss out on a job opportunity.
One big and major rule that cannot be repeated enough is never, ever talk bad about any one of your former employers, it doesn't matter whether it's the honest to God truth you simply do not do this and expect to get the job. Never let them know how badly you were treated. If you quite just say you felt you went as far as you could go with that company and if fired try your best to give a little detail as possible.
