I use mccc to cheat sims to have skills that I think make sense for them. When I added Chuck and Maya from the gallery I gave Chuck some fitness, DJing and dancing. For Maya I gave her some writing, dancing and singing. In my story for them Maya is level 1 in the social media career and Chuck is also level 1 in the Detective career he however want to be a DJ.
I've also gone and raise the skills of some of the other base game sims and even raised some of their careers as for some it doesn't make sense for them to be living in these big houses but have low level career or little to no skills.
