Pros
I had an incredible summer interning at Convergex. The company culture stresses hard work, yet also focuses on maintaining a positive outlook internally. With remarkable new management, who is eager to work with everyone throughout the firm, it is certain the company is headed in the right direction. The employees were welcoming and encouraging, also open to helping out the interns and explaining the several facets that make up the financial services world. I learned more than I ever thought I would, and recommend it to anyone who thinks that may be even slightly interested in finance (in particular sales and trading). You won't regret it!
Cons
There were truly no cons to the internship program. The intern coordinators/team were always ensuring that our experience was going well, and allowed us to meet with any group or individual in the company. In fact, we rotated weekly among different groups- from the sales and trading desk, marketing, credit and risk, and so forth. However, perhaps lengthening the internship or providing each intern with a personal project to present at the end would be helpful! Otherwise, I have no complaints.
