Your first reason should always show fit in terms of professional skills.  This part of your answer lets them know that you are excited about what you will be able to accomplish for them, while still emphasizing what they are getting out of the bargain.  You need to sell yourself

as a business-of-one who can provide a service better than the competition.

 If you can be more specific by actually naming a couple of things you've heard or read about the company's workplace culture that you like, it will help your cause. This is one area where your pre-interview research is critical. Here are a few things you may want to look

for when you research the company : 1. Is this a top company in the field/industry? 2. Is this company known for cutting-edge products or other innovations? 3. Does this company have a great reputation for customer service? 4. Is this company known for being a great place to work?

5. Does this company value and/or provide resources for employee development?

Wrap up your answer to this interview question with something that personalizes it a bit more.  Say something that gives you another reason of your own for wanting this job. This interview answer is a fantastic place to let your enthusiasm for

the job show. It's very appealing to employers, and it gives them one more reason to hire you.
