From a veteran perspective, bartenders and food vendors and delivery people are ideal starting jobs because they teach new players to be social and that interaction is key, rather than your coded job advantages... however I do think from the new player perspective, it doesn't feel very much like escapist fantasy to be directed to a job they very well might be doing IRL to make ends meet.
When people see Blade Runner, they're probably imaging being Deckard and not the guy selling noodles.
The gangs to me are sort of the ideal in this way, since they provide an entry-level role where players are taught by veterans, and get to do something that is thematic an interesting in its own right.
I think it makes sense to create Day 1 jobs for the roles we want new players to fill. Intro tech wiz jobs working at the hardware/tech shop, intro thieves working for the local crimeboss. Maybe security guards for more brick-and-mortar shops (probably the #1 job sought by new players is security-related in my experience).
These don't have to be mechanically any different than a basic bartender job, but I think being able to do something interesting, even if it's just the idea of something, will hook a lot more players.
What other ideas might work to give people something themely to do Day 1?
