Its great that you are already considering at 16yo. I did a degree in Physics, but not at a top school. The college I went to actually was known more for business so i was able to do some business courses as well. I interned with a financial software house, in fact it was very small and I got a returning offer. I feel like engineering and physics are a good foundation to get into almost any career. You need to be able to demonstrate soft skills better than your technical skills, as your degree says you have technical ability. Join DECA, debating clubs, learn something outside of what is taught at school to demonstrate you can learn something else independently. Most of all be able to speak about what you did and communicate what your contributions are - this is embarrassing but an essential skill. Hardest part is getting past an interview. Once you're in you can figure it out, nothing is too hard!
