Pros

I worked at Parexel from 2007 to 2025. It was fantastic place to work and grow. I claim that Parexel had the best people in the industry. Fantastic culture, educated refined colleagues, superior technology.

Cons

The culture of excellence began to erode after Joe von Rickenbach sold the company. Nevertheless, I still believe it remains a strong place to work—provided one has the good fortune of being supported by a competent line manager. In recent years, however, there has been an increase in less capable line managers in leadership roles, accompanied by a noticeable loss of talent.
