I think you misunderstood me. So from the job task itself, I think you can do just as fine as secretary ... But from my experiences, people working in these jobs have more often "more social" expectations on their coworkers. So more gossiping, comforting each other, social talk, spending lunch together, invite themselves to stuff outside of work... O_o Caring about what people wore the day before or if your hair looks great today...
While when working in technical departements, I felt less pressure about such kind of stuff. You can as well have more extroverted people around you in technical job, but from my experiences, there is a higher chance to meet more introverted people.
