Breaking into Pharma

Hello I am a PharmD and I recently got accepted to work at a major cancer hospital in New York. Prior to getting accepted I have worked as a pharmacist at a smaller hospital. After getting my new job my friend reached out to me to inform me that working my new job will open doors into industry. Just wondering how long after starting my new job would one say I can get an industry? And would anyone be able to give me any advice on what I can do to improve my chances for one day getting into industry?
