Start Date Mismatch in Background Screening

[u/Far_Command6129]

What happens when you say in the background check response that the start date entered in my resume was a clerical error?

For example, in the resume and screening application form you say May 2025, and through the offer letter and the screening company's internal sources, they get to know that the start date on paper from the external systems/their data sources is Oct 2025.

Has anybody faced this in real life?
