William Swansen has worked in the employment assistance realm since 2007. He is an author, job search strategist, and career advisor who helps individuals worldwide and in various professions to find their ideal careers.

This is a typical question you will likely receive early in the interview. By the time you've been invited to the interview, the organization has already verified your qualifications for the position. The interview is meant to confirm these qualifications and discover how well you will fit into their company. Organizations prefer people who are passionate about both the work they do and the companies for which they work. Your answer to this should support both of these.

"When searching for opportunities where I could apply my computer science background, your company kept rising to the top of the list. I admire the work you do and your leadership in this industry. I have spoken to several current and former employees. They are very enthusiastic about the work environment, the flexibility they have to explore new ideas, and the collaborative and diverse work culture your organization promotes. I would be honored to become part of your company and to contribute to your ongoing success."

I want to work for the Northwestern Medicines summer internship program because I believe in being proud of where you work. In my application process, I really tried to only apply to companies that I believe do great things for not only their clients but for their communities as a whole. I really believe that Northwestern goes above and beyond for their community in Chicago by having a number of outreach organizations including education, support groups, and donations.

I want to improve my computer science background by gaining some experience.

Rather than highlighting what you'll get (experience), focus on how your unique skills, experience, qualities, and education will benefit the employer. In other words, how will hiring you help them? Also, discuss what appeals to you about the company, its culture, and the role itself.
