Employers expect employees to stay up-to-date in their respective fields, and today's technology makes this fairly easy! List several ways you access industry resources and stay on top of trends. Tell the interviewer about those daily update emails you receive from professional organizations, conferences you attend, seminars you have taken, and professional organizations you are a part of. Lastly, it's a great idea to ask the interviewer what resources they refer to for industry trends. That question can start up a great conversation, and you may learn a thing or two as well.
