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.
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.
