Your interviewer asks this question to determine whether your goals align with theirs. A candidate who merely has an alignment of skills and is looking for any job anywhere will probably be viewed as having little to offer. Such an individual would be viewed as simply looking for a regular paycheck, might lack loyalty, and could end up with the highest bidder. Such an individual would likely perform the bare minimum, merely adhering to their job description. However, your interviewer's goals are to find the best person for the job who will collaborate and innovate with their teams, build relationships, and embody and represent their company's culture, values, and brand. So this question is all about what you uniquely have to offer them. As Mahatma Gandhi once said, "The best way to find yourself is to lose yourself in the service of others." So when answering this question, inform them of how their company is a place you would take pride in working with and how you are uniquely positioned to be a stakeholder in your mutually continued success.
