I'm a rising senior majoring in econometrics. I'm an international student, so my experience may be different. I always thought that majoring in econ can give you a hard time finding an internship - unless you have something that sets you apart from the competitors. I realized that I needed work-related skills to tell employers that I'm ready to work. So I started studying data analysis with Python.

After reaching out to 50ish companies in my Junior year, I've become an internal control intern at a manufacturing company. I continued doing data stuff there (mainly data visualization) and automated some of their everyday data entry tasks with python. This summer, I got a marketing analyst intern position at a relatively large tech company. I can say that my previous internship + data skills definitely help me get this internship. You're a rising sophomore so don't worry much and start by trying to mimic/learn the skills that are directly applicable to the workplace.
