This question is similar to asking what your work ethic is. Employers want to know that you have a strong work ethic and that your values match the values of the company. With this question, the hiring manager can determine what kind of person you are and what matters to you in the workplace. Everyone has their own set of values; you just need to articulate yours during the interview. Speak to your work ethic, integrity and character. Keep it positive and related to your work. If you know the company culture and what values they profess, you can highlight your own values that align with theirs. Working for a company with similar values will help you to be satisfied in your job. If you work for a company that only values profit margins, and doesn't allow any flexibility for employees with families, you may find that you're miserable in the job if those aren't things you value.
