I love working there,, I love to make the restaurant happy and guest happy,, I had so much fun

Most companies use a third party outside agency to conduct back ground checks then forward copies of the results to employers and applicants. Did you sign a waiver at McDonalds to allow them to conduct a background investigation? Check the agreement if you have a copy or go back to the restaurant and ask the manager.

I'll also add McDonalds Career FAQ page below so you can look into the companies recruiting and applicant processing details for more answers to your question. Thanks
