The article provides a subject-oriented insight into the living environment of young adults and examines professional development processes in the context of a gender-atypical career choice. As with Richter & Jahn (2015), there is evidence that a gender-atypical career choice of young men and women has specific causes. The question arises, why young people, contrary to social conventions, opt for vocational training that is not gender-specific, how their private and professional lives promote, reward or sanction it, and how this affects their professional identity development. Against the background of the work of Schütz (1957), Marcia (1966) and Gottfredson (1981), theoretical considerations lead to interviews with eleven trainees in non-gender-related occupations. The findings show that four different types of "unconventional" can be described along with different characteristics.
