It's been over three years from when I used to ground handle them at my airport. Business casual, laid back put. 91 flying. Start in the EAU in the morning flying a trunk airline type route with 5-8 short legs dropping off all sorts of product support, manager, quality control employees at each airport. Rental cars waiting for employees at the FBO. Most weekday flights the plane is on the ground for maybe 5 minutes as it unloads, sometimes not even shutting down the #2 engine. Turn and burn for the most part. SICs didn't get typed at least when I was trying to get on, captains seem to be pretty happy. Only issue is there was no going through the back door to get a job, had the chief pilot look at my resume and he handed it back to me saying HR has to do all the hiring, they can't do it themselves anymore.
