Hamad Medical Corporation

Hi, I'm interested in working in Hamad Medical Corporation. I served as locum physician 2 years ago, I told them about my intention to work in HMC. The HR told me that there was vacancy and my papers was forwarded to credentialing section of HR.
a. Is credentialing same with  primary source verification?
b. when they say then my papers are already in credentialing, does that mean, they're planning to hire me if my papers are verified?

i hope you will have on boarded in HMC now . My suggestion to every one sit tight here process take time
