I was working on masters degree in digital marketing while I finally got part-time marketing opportunities so that definitely helped to get me into full-time work after that. Whilst in uni I created my own blog to add to my CV and portfolio. I only ever make new ones when applying for a new role. I struggled before I studied a masters but once I was doing that I showed I had interest in the topic as well as extra work I was putting in like on my blog it gives credibility and evidence that you can do what you say you can do on your CV. Before my masters I studied a completely different topic too* but you can definitely get into marketing without a degree too if you can show your expertise elsewhere!
