Fully expected to see Sociology here. It's not a money maker degree and I also went to a left leaning university.
If I had the time again, I would have done English (my passion). The same/more jobs would have been open to me.
I don't know if I 'use' it but I apply it/skills I learned.
If I had a chance to change my career...it's not so much that I would do anything different but I would have cracked on sooner.
I didn't apply to any grad schemes as I did not feel good enough/thought it was too competitive for me. I was so unconfident.
I temped for ages after Uni, then did more jobs underusing my skills, before eventually giving myself a chance to look at what I enjoy/am good at/opportunities, and going for it.
I think Uni is a good choice. Jobs with work life balance- that is the million dollar question. I think you have to make work life balance but some careers are better than others. Essentially, at some point you have to get more technically specialised, or get more generalist managerial skills, to progress. It helps to look for careers with structured pathways for progression.
Probably a solid English or humanities degree or a science degree will get you furthest.
