When they ask “how did you hear about the position?”, the interviewer just wants to know if you’ve taken the time to research the company and if you have a genuine reason for wanting to talk with them. Mention a product, a mission statement on the website, a reputation for talented employees, or whatever else seems applicable to that specific company. Come up with a great reason. Don’t make it seem like they’re just one company among many. Or that you’re sending your resume out to them for no particular reason other than wanting a job. You should hire me because my experience is almost perfectly aligned with the requirements you asked for in your job listing. I have seven years’ progressive experience in the hospitality industry, advancing from my initial role as a front desk associate with Excalibur Resort and Spa to my current position there as a concierge. I’m well-versed in providing world-class customer service to an upscale clientele, and I pride myself on my ability to quickly resolve problems so that our guests enjoy their time with us.
Remember that employers hire workers to solve a problem, whether it’s boosting sales or streamlining processes or building a brand. Your goal when making your pitch is to show that you’re the best person to solve that problem. Interviewers ask questions about why you should be hired to measure how you qualify for the job and fit in with the company.
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.
