Pros
Goldman Sachs, wherever you are, has a strong culture of simultaneously being excellent yet humble. People want you to succeed and will give you every ounce of support that you need to move to the next level of performance and/or responsibility. If you do a great job in any area of the firm, Goldman supports the ability for top analysts to be mobile across divisions and responsibility levels. After doing a summer there, it really taught me how to carry myself professionally, work as part of a team, and become extraordinarily more self-aware about my strengths and weaknesses. Overall, it's a great place to work.
Cons
As with any top-tier financial services firm, the hours are long, and it is easy to lose work-life balance. This is especially true for a summer intern, who is seeking to prove himself or herself. You must be aware of office needs and fit your own needs into the schedule--management does care about this. Also, this is a high performance culture where any lapse into mediocrity or making minor errors is not tolerated. Goldman, therefore, can be a rough place at times when you slip, which you are bound to do at some point. The key is to stay cool and take feedback in strides.
