This is a common and tricky question to answer. No-one can really predict the future. Think carefully before answering - it could either show you're focused, ambitious and a hard worker or it could imply that you're directionless or unmotivated if you answer: I don't know.

Most companies are looking for employees who will stay and grow with the company. An answer that reflects this is advantageous.

Think about the job and how the experience and/or training will help your career. Will it help you move forward and upward? Do you have goals you're working towards? Are you willing to learn?
