Summary List PlacementWhen she was just starting out at Goldman Sachs in 2007, Jane Dunlevie leaned on investment-banking exec Kim Posnett to show her the ropes. Back then, Dunlevie was fresh out of college from Stanford and an analyst at the firm. In a recent call with Insider, she recalled spending long hours alongside Posnett, her former boss, and learning from her. "I vividly remember sitting in a room with Kim, marking up a deck and explaining analysis," said Dunlevie, 35, who today has become one of Goldman's youngest partners, and serves as its global co-head of Internet investment banking.
