Was not too hard to get. NASA looks for students of various majors in nearby universities with enough skill to do Systems Engineering work. One good recommendation and a well edited resume in the right hands can get you an interview. Just know what the role entails and satisfy all the requirement such as GPA. Some meetings with NASA employees to know the position well helped lots. The interview was mainly just to see how interested I was in this line of work since Systems Engineering is such a broad field.
