What your interviewer is really trying to do with this question—beyond identifying any major red flags—is to gauge your self-awareness and honesty. So, “I can't meet a deadline to save my life” is not an option—but neither is “Nothing! I'm perfect!” Strike a balance by thinking of something that you struggle with but that you’re working to improve. For example, maybe you’ve never been strong at public speaking, but you've recently volunteered to run meetings to help you be more comfortable when addressing a crowd. Companies ask this for a number of reasons, from wanting to see what the competition is for you to sniffing out whether you're serious about the industry. “Often the best approach is to mention that you are exploring a number of other similar options in the company's industry,” says job search expert Alison Doyle. “It can be helpful to mention that a common characteristic of all the jobs you are applying to is the opportunity to apply some critical abilities and skills that you possess. For example, you might say 'I am applying for several positions with IT consulting firms where I can analyze client needs and translate them to development teams in order to find solutions to technology problems.'”
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.
