ITA Checklist

[deeplubana]

Hi all,
Received ITA checklist asking for documents.In employment section it says.-
Please submit an original or certified copy of your full employment agreement including your offer letter (if you have one) and a full job description. It is also useful if you submit a letter from your employer explaining what your duties are.So,how important is this letter from employer as my company has already given me a full job description. how it will hamper my application if i don't submitt one as it is not mandatory i reckon.Moreover does it mean that job description is not enough for INZ to assess one's application.Anybody can help me out with this plzz..
