May Petry, Vice President of Digital and Growth Marketing at MongoDB, emphasizes the importance of defining personal values, being authentic, and "getting comfortable with being uncomfortable" as a leader. She shares her experiences growing her career in leadership, including overcoming intimidation and loneliness as a woman in a male-dominated field, and learning to use imposter syndrome to fuel growth and collaboration. Petry advises building a team by being a role model, providing individual growth plans, and taking charge of one's own development, while also encouraging women to find supportive networks and be kind to themselves as they pursue leadership roles.
