That's worrying for me as I'm the same age as you and I've done the reverse of what you have done.I can only speak for myself, but I spent 10 years working in this industry and I'd recommend you avoid it like the plague. Met some great people, but the way you are generally treated in these jobs is appalling, primarily because you are instantly replaceable, so they know they can treat you like shit and get away with it. I was lucky enough to get out, although it was partly because I took my last employer to court for treating their staff so badly. Unless you were one of the CEO's pet employees, which involved kissing his arse, there was never any chance of promotion. And I saw this at multiple companies. One of the major problems you will find is that once you've been doing this for a little while, your degree will suddenly essentially become meaningless and you'll only be able to find work in this sector. I got out at the age of 33 and ended up going on to get a degree and a phd and now I work in medical research. Walking out of that company/industry is the single best move I ever made in my career.
I got a degree and got a job with it and stayed in the profession for 11 years.
Now I've moved completely away from it and moved to b2b sales.
I did apply for other roles (recruitment and managing a business) but was told that I didn't have the sales experience.
I think I would like to end up in recruitment in a few years but I'll see where it takes me.
The place I've just started at is a huge company so lots of opportunities for progression so I may end up staying for a long time.
