Example: “I would say that as a security officer, I’m vigilant, proactive and committed to ensuring safe, secure, and orderly environments. In my last incident response rating, I received a 99% against the team average, which has been at around 97% over the past 3 years. I like to be thorough, documenting all incidents. I’m also a lifelong learner, always seeking out the latest security equipment and techniques to patrol buildings. I frequently make suggestions to management about security improvements and changes as my motivation comes from making a meaningful contribution.”
They fired me because I had a different opinion than the director of the company. Nothing wrong with him—we just had a different philosophy of leadership, and how things should be done. Maybe he was right, maybe I was—only time will tell. But I do not want to live in the past. Now I am here, looking for a new challenge, and an opportunity to help your company to prosper.
Employees who love their jobs naturally recommend their company to their friends and peers. The same is true for people in leadership positions -- people naturally try to bring on board talented people they previously worked with. They've built relationships, developed trust, and shown a level of competence that made someone go out of their way to follow them to a new organization.

a Job Applicant Should Not Ask Questions During an Interview

Even so, if you're asked, provide a sharp, on-point answer. Be clear and precise. If you're a great problem solver, don't just say that: Provide a few examples, pertinent to the opening, that prove you're a great problem solver. If you're an emotionally intelligent leader, don't just say that: Provide a few examples that prove you know how to answer the unasked question.
Any candidate can read and regurgitate the company’s “About” page. So, when interviewers ask this, they aren't necessarily trying to gauge whether you understand the mission—they want to know whether you care about it. Start with one line that shows you understand the company's goals, using a couple key words and phrases from the website, but then go on to make it personal. Say, “I’m personally drawn to this mission because…” or “I really believe in this approach because…” and share a personal example or two.
