have stamped H1B. Can I interview for H1B position while I am in US on B1


I have stamped H1B visa.

I am coming to US on B1 Visa for some other work.

While I am here can I interview for any H1B position.

If I get through, can I come back to India and then travel back to US for the H1B position.

I dont think I need to go for H1B stamping again.

Please let me know your thoughts.
