Your cover letter and resume usually provide all the information which a prospective employer will use to decide whether or not you will reach the next phase in the application process: the interview.
This is one of the most frequently asked questions in a job interview. First, list some strengths you have and make a script that includes the information you want to convey. For example, you can start off talking about your past experience and proven success:
"I have been in the customer service industry for the past five years. My most recent experience has been handling incoming calls in IT industry. One reason I particularly enjoy this business, and the challenges that go along with it, is the opportunity to connect with people. In my last job, I formed some significant customer relationships resulting in a 25 percent increase in sales in 5 months."
Then you mention your strengths.
"My real strength is my attention to detail. I pride myself on my reputation for following through and meeting deadlines. When I commit to doing something, I make sure it gets done, and on time."
Then you conclude with the statement about your current situation.
"What I am looking for now is a company that values customer relations, where I can join a strong team and have a positive impact on customer retention and sales."
When you answer this question, it is the best to focus on tasks, rather than company policies or people. The good response would be:
"I've been very satisfied with my jobs. I've been able to work with some interesting people. I have to admit, I did have a job where there was an inordinate amount of paperwork. Because working with people is my strength, the paperwork really bogged me down at times."
Through this question, you can show your interest and enthusiasm for the company and what it stands for. You can also demonstrate how you envision you could be a member of the team.
"Based on the research I've done, this company is an industry leader. When I visited your Web site, I found some impressive information about future projects you have planned. I was also impressed with the founders' backgrounds and the current financial statements. This is the company I've been looking for, a place where my background, experience and skills can be put to use and make things happen."
