H1B Visa Stamping - Employment Agreement Letter

[l1toh1us]

Hi,
I am going for visa stamping next month and from all check lists I came across in forums, there is a mention of "Employment Agreement letter". Is it the same as Offer letter or Employment verification letter describing the role and job duties?
Can someone please clarify.

Thanks
