For the record, the ones we definitely know about are (thanks to the wiki):
- Macrodata Refinement
- Optics and Design
- Wellness Center
- Mammalians Nurturable
- Choreography and Merriment
Possibly also departments:
- Distribution Supply
- Disposal and Reclamation
Mammalians Nurturable definitely seems like the choice when considering that it will realistically be your entire life. MDR is a pretty basic desk job, which is pretty good if you get to go home later, but not so good if it’s all you’ll ever do.
Optics and Design is another strong one. Like MN, you’ve got a large peer group, so hopefully you can find somebody whose company you enjoy. Plus, the job has you working with stuff that changes from day to day, unlike MDR where you just do the same thing for endless hours.
Yeah, I’d go with O&D. You’d see lots of interesting objects (far more than employees from other departments would ever see), and presumably also do some design work - it won’t ever get boring! Unlike staring at numbers all day.
