Before the interview, think carefully about why you want the job you are applying for. Think about possible ways you could learn and grow from working in that position. Think about how this job will support your long-term goals. Think realistically about where this position could take you and answer along those lines. If it's early in your career, It's okay to say that you're not quite sure what the future holds, but that you see this experience playing an important role in helping you make that decision.

"In five years, I'd like to be in a position where I know more about my long-term career aspirations as an engineer. By then, I will have had experience working for a large, multi-disciplinary firm and know more about the industry overall. I'll have grown my technical skills and learned how to take feedback from clients and incorporate it. I'll also have had the opportunity to work on different types/scales of projects--including roads, bridges, and buildings--for a variety of clients to see where I really feel at home before settling on a long-term focus."
