How long will it take Cheng Fei to get the results after the interview?

The time to give the interview results depends on the specific situation. Some large companies have to wait until all the people in the country have finished the written test before selecting outstanding talents, so the result may be late, about a week or two, and some companies that don't need to recruit too many people will return faster, about two or three days. But if you haven't answered the phone call or email for two weeks, ask the internal recruiter.
