In one sentence, describe what the following article is about:

Before you enter into the interview take some time to research the company.  Having some in depth information about the company will allow you to present yourself in a way that fills their needs, demonstrates your compatibility with the culture, and will let you think of questions to ask during the interview.  Interviews are two-way processes.  Don't forget that you can evaluate the company as well. You might want to ask what the company's goals are for the future. Present yourself in a way that shows you being a good match for the organizational nature of the company. Pay careful attention to the language used by the organization or the job offer and try to mirror it.  Use words like "motivated", "focused" or "reliable" to describe yourself. Although your interview may vary slightly due to the nature of the the position you are applying for, most interviews have some common elements to them.  By following the general interview techniques you can help make sure that your interview is a successful one.  Leave yourself enough time to show up early. Dress appropriately for the position and work culture you are applying for. Be courteous and polite to everyone you meet even if they aren't directly interviewing you. Practice your interview before hand. During the interview you will want to focus on what it is exactly you are offering to bring to your new employer.  Although you may have outlined this on your resume you now have a chance to fully express why your skills are needed and how you will benefit the employer.  Discuss your skills in a way that shows how they will be a perfect and unique fit. For example, you might say something like  "When I ran my own firm, I successfully landed X client despite their initial hesitance to go with a small business. I know that I can use the same persuasive ability to help your firm." Showcase your marketing skills by demonstrating a successful campaign you ran. If you did have employees or contractors, talking about how you managed your team can demonstrate your leadership capabilities. Even if you have included in your resume a brief description of why you are seeking employment now is a great time to explain this in more detail.  Your employer may be worried that you will not be a good fit or team-member because of your work history.  Use this time to demonstrate how excited you are about aspects of working with others again.  Make it clear that working for or under someone else is not a problem. Expressing enthusiasm about working on a team again can also be a good idea. You might try saying something like "As my own boss, I found that I missed the creative energy I get from bouncing ideas off other people. I am looking forward to once again being part of an energetic and dynamic team."

Summary:
Research the company. Follow some of the standard practices. Represent your strengths. Expand on your reasons for leaving self-employment.
