AIG was not transparent about the path to full time employment. They definitely hired more interns than they could take on for full time roles, which meant that the final decision was not based on performance. Many high performing interns did not get full time offers. Offer status was also communicated two months after the expected date.
Also, many full time employees acknowledged that politics play a huge role at the firm.
It was also very difficult to see the big picture of what you're doing at the firm. The structure of the firm is very complex, and it was difficult to get information about the organizational structure from managers. Each team seems to operate as its own entity, and there doesn't seem to be a sense of unity throughout the company. Instead, each group has its own culture and own methodology.
Managers were often too busy to manage the development of their interns, and I had very little interaction with my manager throughout the summer. I didn't get the sense that managers cared about our growth and success.
