How to refuse if you promise to go for an interview and then don't want to go?

You can answer this question. Thank you very much for your interview invitation.

Because I am eager to apply for a job recently, I have also participated in interviews with other companies before. After arranging an interview yesterday, a company decided to hire me.

After careful consideration, I decided to give up this interview opportunity given to me by your company. I'm terribly sorry. Thank you very much for recognizing my ability and giving me an interview.

I hope I can understand the inconvenience caused to your company. I believe that your company will find a suitable candidate as soon as possible, and I wish your company a prosperous business.

Tell me honestly why you didn't go to the interview. Don't lie. HR has seen many people and can tell at a glance whether they are lying or not. Then take the initiative Don't wait for the other party to contact you, after all, it is you who stand up.

Finally, I want to apologize. You could say that. Sorry, because of my own reasons, I won't attend the interview in your company. I sincerely apologize here and hope to get your understanding.
