Competition for junior UX product design roles is fierce! Even internships attract talented, skilled and qualified people. Make sure your product design portfolio is securing you a place in the first round of interviews. I have seen dozens of applications in the last couple of years. Attaching a static mock-up with a CV is not enough to pass initial screening. I share here the essentials to include in your application and what things help filter out the maybes from the discard pile. I hope this helps you see your application from the perspective of the hiring team and gives you some ideas about what to revisit or polish. Best of luck!
