Traditional academic career paths are over
The career path in science of being a student, grad student, postdoc, lecturer, professor and then retired professor is over. Sometimes even at the same university. Nowadays, this pathway is interrupted by periods of work for an industry or entrepreneurial endeavoures. Some of the stages of traditional pathway are doubled, or even tripled. This is especially true for postdocs, with more and more junior academic positions requiring you to finish 2-3 postdocs before applying.
