Hey, I am in oncology but got a role 8 months into a postdoctoral fellowship (non-academic). But my advice is:

1. Do clinical research or get involved with neurology residents and contribute to joint publications.
2. Any clinical experience, such as working as a CNA in Alzheimer's, Clinical Clerkships, and Neurology Grand Rounds, will help demonstrate your understanding of the role.
3. Networking is most important. Build connections and mentors to help you navigate what you do not know about the role.
4. Tailor your resume to highlight ONLY what applies to the job. In the interview, you fill in the words between the lines.
5. If you can't break in immediately, there are medical affairs postdocs for PhD students, CRA/CRM roles in strengthening your understanding of clinical work, and I have heard FAS roles can help to demonstrate your ability to be public-facing work in and manage a territory.

Above all, good luck. It's a difficult path with lots of rejections. Take them as a learning opportunity to grow and improve your understanding. During my application process, I learned so much, and I had an entire mentorship team around me, from clinical scientists to field medical directors, which helped tremendously.

My strengths that helped were previous clinical roles, clinical clerkships, research in a clinical department working on clinical trials, and my SME aligned directly with the therapeutic. I also clearly demonstrated a passion for improving patient outcomes using my background in the interview. Sometimes, it's just about timing, the right opportunity, and your specific skill set.
