Please accept an interview with Chongqing AVIC Food Company! I'm a pilot and I'm in charge of plane meals. I wonder if the diploma of private schools can pass?

If you mean the food safety administrator in charge of airplane meals, it has little to do with whether your diploma is public or private. After admission, take part in the food safety training of the Food and Drug Administration of the United States, and issue a certificate after passing the examination, then you can take up your post.
