Confusion about filling(applying) to the company

Hello frnds,
I got selected in campus only. now I want to apply to the companies .while applying to the companies , we are asked to write the offer letter got or not . My question is , if u keep offer letter while applying , will it be problem or not . will they call or not . ?

if u have ur offer letter then share it with them.

by seeing offer letter …they may not call us…is it correct ?

no its not like that…please share ur offer with them
