The interviewer asks this question to ensure you are comfortable with the hiring process and that there are no red flags or concerns that would prevent you from passing a criminal record check or education verification. The organization must maintain a safe and trustworthy environment, and a thorough screening process is necessary to achieve that goal. If you can successfully pass a criminal record check and education verification: 'Yes, I am happy to comply with any background checks required. My record is clean, and my education can be verified.'
Suppose you cannot successfully pass a criminal record check and education verification. In that case, you want to be very upfront: 'You are welcome to conduct a background check on me. I will disclose upfront that I have a DUI on my record from 2009. This does not affect my ability to travel for work, and I no longer have any restrictions on my driver's license.'
