Summer Analyst Background check: Employment information inputted by YOU or pulled from bank application portal?

Hey all, I had a question regarding the background check for the summer analyst role, just to make sure everything goes smoothly. **Does the 3rd party verification company pull employment information and details from the resume submitted to your bank or do you input the details into the 3rd party verification company's portal? ** I have made some significant changes to my resume and have two additional roles (and removed one) that are not on the resume submitted with my IB SA application. I want to make sure that there are no issues that arise form this.

Thanks in advance for the help!
