Hands on experience is highly valuable. Don’t worry if your subject is in something not related to marketing. Hubspot and Google certifications are easy to get and can be a nice boost.
Side projects will be really welcomed. Always use specific results and KPIs in your CV, marketers love seeing data.
I would say pick a specific aspect of market and continue developing that skillset. For example it could be copywriting, social media, design, events, brand marketing, analytics or campaign management. But you should also be comfortable with other aspects of marketing and willing to adapt to new trends.
