Best: flexible culture that allows each person to take on projects they are interested in and run with them. Promotions are transparent and feedback is detailed, thoughtful, and frequent. New hires are paired with a mentor, and these relationships usually remain close long after training ends. Career mentors act as lifelong "cheerleaders" and advisors. Leadership is thrilled to help employees get their next dream job if they decide to leave, and offer resources to transition out when an employee decides to do so.

Worst: limited geographic locations, so few international opportunities
