Public Trust Clearance Questions

Hello everyone
I have a quick question about public truest clearance process.
Do federal gov investigator ask my current employer about my previous employer?
I did not list some of my past experience (within last 7 years) to my current employer.
My only concern is if the officer asks about my past employers from my current employer information will not match.
Note: I put all the details about my employment history to SF85P and did not drop any past employers.
Thank you!

No, we don’t. We try to gather information not spread information.
