In addition, it is also important to highlight your passion for UX design and how it can help the company achieve their goals. For example, you can mention how your design thinking can help the company solve complex problems or improve the user experience of their products. Ultimately, your goal is to show how your skills and passion can benefit the company and help them achieve their objectives.
