I have a business degree and a successful career in Marketing and Digital. I actually got my first jobs in my field, which I did whilst studying at university in my spare time. I got it through working in the local pub and meeting customers whilst doing my degree.
I also went door to door and got a saturday job at a lettings agency which taught me sales and customer service.
I worked at a double glazing firm, a record company, a lettings agency, I temped reception roles at Sainsburys head office with a shoddy temping agency. I worked in retail, bar work and night clubs. I worked at Phones 4 U and a band agency, I did work experience unpaid at a variety of companies that I approached. All of this before I left university.
The soft skills I learned, the networks and business accumen I gained were what actually got me into my career. Anyone can get a degree but the other stuff you also need to learn before you can land a decent role.
I would say to just start work in anything, build up the soft skills and networks through other roles, it might take a year of random roles before she gets something meaningful.
I remember when I left uni going to grad recruitment days with 30 people trying to get the same job, like hunger games. Mostly I didnt get the job but after trying and trying and building up more experience I got a really great role.
My advice would be to think creatively, go for everything, find any other work to do in the mean time, build networks and meet people. Sign up for free business networking events, just go to them and speak to people.
I now recruit for grad roles in major blue chips and often sit on the panels. There are grad roles out there, but you wont be getting them if you just have your degree and not any work experience. But by work experience I mean, either by starting your own thing ( a blog or etsy shop or whatever) or real world work experience which doesnt have to be in the field or in an office, could be bar work or temping etc just being able to show that you have real world experience and can deal with people and work places and teams and targets is really key.
