Overall it was a great learning experience. Everyone I worked with was extremely smart, competent, and kind. I attended a conference in Florida where I interacted with clients -- this was probably the highlight of my summer.
What I wish was different
I would have liked more exposure to the work of full-time Business Analysts earlier on in the internship. However, I was able to gain this exposure by just asking my mentor.
Advice
Approach everything with enthusiasm and seek to take on additional tasks. Spend a lot of time talking to people, both taking advice and trying to understand different professional roles.
