Some of the main qualities I’d recommend emphasizing on both your resume and interview would be the whole UX process itself. You want to make it clear that, while there is no strict formula to tackling a UX project, you understand the importance of the functions / structure of the process as a whole. Every interview I had someone asked me “what does your typical process look like?” I recommend thoroughly explaining user research, personas, flow charts, wire framing & prototyping, and usability texting (just to summarize). I’d also talk about how you incorporated all of this in a project and talk through your work and the things you learned were or weren’t working while going through the process.
What’s your major and what classes have you taken that could help you with this role? What skills have you learned and how have they helped you grow as a designer?
Another thing I would emphasize is your knowledge of design tools and resources - do you know how to use Sketch, InVision, Axure RP, Principle, After Effects, Illustrator and Photoshop? Talk about it! And how do you get inspired? Are you an active member of Behance, Dribbble, or Medium? Try and immerse yourself in various design communities, not just for an interviews sake, but for personal growth as well.
