Advise Required for Stamping Related Queries

I am working for one of the top 5 IT companies in India, they filed H1B for me to fill a opening position within the organization, we are not processing for any client as I will be working for multiple clients. My petition was approved w/o any RFE and I am planning to go for stamping in the coming weeks. What kind of questions should I expect in the stamping interview? What are the chances for denial?

I am working for the same company for 7 years and already worked in the US for the same company for 3+ years on L1B for 2 clients.
