It was a very dynamic job that challenged me and pushed me to grow my technical skills and intuition about the financial markets. Projects were just like the sort of work done full time and had real potential to generate PnL.
What I wish was different
I wish the internship had been in person, but props to the company on not cancelling and delivering a solid online program.
Be prepared to learn a lot and work hard. Ask lots of questions! There's no such thing as a dumb question when the problems you are working on are hard problems.
