Demonstrate your ability by doing actual work relevant to the role you seek, as it not only proves your capability but also helps you assess if you enjoy and excel in the field. Create a portfolio project showcasing your skills, like a blog for writers or projects on GitHub for software engineers. Engage in the Pre-Interview Project by researching the role, identifying problems to solve, developing solutions, and presenting them to the company. Consider offering a trial period to showcase your skills to an employer who is hesitant. Apply for a nearby position within the organization if you can't secure your desired role immediately, as it allows you to prove your motivation and fit for the culture.
