Background check

By | April 16, 2018

I recently accepted a full time position with one of the big 4, and they will soon do a background check on me. However, I have a concern. I have had an unpaid internship in college and I did not request to work authorization for it ( I am an international student in the US). Will they probe too deep and ask the school about the paperwork, or just call my manager and ask him the details, because my manager can provide the details.
