I promised someone an interview, but I sent a message saying I wouldn't go, but my boss said I was crazy and disturbed his plan. He also said that I was rude and had no quality. Am I wrong?

Personally, I think you are very polite.

After all, the interview is the choice of both parties, which does not mean that the boss made a unilateral choice.

Besides, you have sent a message that you are not going to the interview, which is better than those who promised to go to the interview but stood me up without prior explanation.

Compared with what the boss said, your behavior is nothing. I believe you don't want to follow such a boss.

So, for this matter, you can relax a little and don't care too much.
