Archived Ad: Econ/Math Major Seeks Internship and Grad School Advice

I am currently a junior majoring in Economics and Mathematics, and also considering a minor in Business. I have had some internship experience in banking where I assisted managers and communicated with clients as well as a journalism internship that helped hone my interpersonal and research skills. I am interested in intern opportunities during the spring or summer in any organization┬árelating to economics or math, especially consulting, analysis or research assistant. I’m open to most locations in the U.S. and China and would greatly appreciate any advice on where to start and how to reach out to organizations. Additionally, I really want to know more about the application process of applying graduate school. What was your experience applying? If you could go back to junior year, how would you have timed your graduate school applications? Or would you have decided to work immediately after graduation? Thank you very much for taking time to look at my Wisdom Wanted Ad, I look forward to hearing back from you.
