Hi I did engineering at aberdeen uni and work in Oil & Gas so hope can help
1) aberdeen is a great place to be a student, great facilities (library, sports, campus etc) in medieval campus. Lots of societies and is definitely agree about high student satisfaction. The non-uni side of town is more run down though. Earth sciences are very well regarded though
2) hillhead halls are basic but decent. You can if struggling stay there in 2nd year but most people stay with friends. Also can move into powis place, Fraser studios, causeway view, old firehouse from 2nd year onwards which are private halls. You’ll definitely manage to get accomodation somewhere.
3) aberdeen uni really helps support you getting a job. But getting internships is definitely on you, they advertise online within the uni, but you have to make the effort to apply and find some opportunities. Being at uni in aberdeen shows you are willing to live in aberdeen if you’re looking for graduate work here. It’s a remote part of country so all employers here want a graduate who will stay in aberdeen for more than just 2 years. If you go to uni here it shows you’re committed to the area and have links / friends. I would say that as a geologist your best industry chances are carbon capture. Speaking as an oil and gas engineer. I am seeing first hand how little need there is for petroleum geologists from 2027 onwards in UK North Sea. There still will be a need for them, but competition will be very fierce. There WILL be demand for carbon capture geologists, but not as much money as petroleum geologists though. There will still be petroleum geologist demand internationally though and Aberdeen has a name Europe’s energy capital so the university will have power if you want to work as a petrolum geologist
Hope this helps
