* Test Pilot: This is his most common civilian job. He works for Ferris Aircraft, testing experimental aircraft. It's a job that requires his courage, skill, and ability to push boundaries, all of which translate well to being a Green Lantern.
* Military Officer: He's also been shown serving in the US Air Force, both before and after becoming a Green Lantern. This experience further enhances his leadership and tactical skills.
* Artist: In some versions of the Green Lantern mythos, Hal Jordan is a talented artist. This artistic side highlights his creativity and ability to express himself in different ways.
It's worth noting that Hal's civilian job can vary depending on the specific comic book run or adaptation. However, his work as a test pilot is the most consistent and iconic aspect of his civilian life.
