UVa ECE master of engineering的ps说得太宽泛了，怎么写啊？

我申ECE的 master of engineering。他家要我上传一篇这样要求的PS：

Please describe your objectives in seeking an advanced degree. For example, please include information regarding what you want to do five to ten years from now, and your interest in industry or academics as a career.

求指点，字数多少合适？要写科研经历吗？ps：这个 master of engineering是without thesis的。
