Pros

Over my tenure, I had the opportunity to work alongside highly talented and mission-driven colleagues dedicated to improving patient outcomes. The organization provided exposure to cross-functional collaboration, leadership development opportunities, and meaningful work supporting healthcare providers, patients, and community stakeholders. I appreciated the company's commitment to innovation, professional growth, and serving patients through scientific advancement.

Cons

Like many large organizations, priorities and organizational structures evolved over time, which occasionally created uncertainty and changes in responsibilities. Decision-making processes could sometimes be complex due to the size of the organization, and navigating multiple layers of stakeholders occasionally impacted speed and execution.
