Job title on COS and Offer letter are different

[samrajan]

Hi,

I've a query here.
My employer issued a COS and the Job title specified in COS is "Associate" and the actual job title as per Job offer is Senior Associate(it's the Grade) and application is already submitted.
My query is, Would it be a problem later when I start working as Senior Associate under the same employer.? or would be there any problem later?

Looking forward for a response.

Thanks and regards
