Kroll Background Check - References

#1

Hi,
for the Kroll Background check they ask you to give two references that you are affiliated to either through eduaction or work. How should those be chosen? Does anybody know what kind of questions they should be able to answer about you?
Thx

#2

Choose the person who will say good things about you. If they didn’t specify anything on your references, two professors will be enough .

#3

Do you guys know what Kroll asks for?
