While your interviewer can see from your resume and your experience that you have the technical skills to succeed in this role at New Relic, this question is allowing them to dig more into your skill set by having your talk about your other skills and qualities that you feel will make you successful. When thinking about the overall duties that you'll hold at New Relic if hired, try to touch on some of the following points: critical thinking, analysis skills, time management, problem solving skills, communication skills and troubleshooting skills.
"As I look back on my career to this point, I can really attribute much of success to my time management skills and my communication skills. As a system analyst, I work with many people on many different projects. My excellent written and verbal communication skills allow those that I work with to understand me, my needs and provide information to me in a clear and concise manner. Then, when handling multiple projects, my time management skills involve careful project tracking, setting goals and delegating tasks when needed."
"In my short time working as a system analyst out of college, I've had the opportunity to do a lot of self reflection based on the teams that I've been a part of. In a team based atmosphere, I find that my critical thinking skills put me in a position to lead groups in planning and development phases of projects. Then, because of my technical knowledge in software applications and networking, I have developed great troubleshooting skills that I'd be able to contribute to the team here at New Relic."
