This companion report to Common Careers of Physicists in the Private Sector is one of a set of three that describe the work that PhD physicists do 10 to 15 years after earning their degrees. It is a compilation of the comments that these physicists wrote in response to the open-ended question: “Briefly describe your duties and responsibilities in your current job.”  The comments are organized into the eight types of private-sector careers held by PhD physicists in the US. These eight types of careers are the organizing theme for each of the three reports. The comments provide readers with a vivid picture of the breadth and variety of private-sector job duties and responsibilities reported by mid-career physicists
