How to cancel the interview politely

1. Write back to him directly: "Thank you for your favor. After careful consideration, my ability doesn't match the requirements of your company. In addition, I have my own ideas about the current development direction. I hope to have cooperation opportunities in the future. "

2. For the company that chased me, I can directly say that I found a job.

For companies with good attitude, it can be said that I will reconsider and contact if necessary.
