HR asked me to call the interviewer, but I called 20 minutes late at the agreed time. I was hesitant at first, but it was a lie, and then I called.

Whether it’s true or not, it’s your problem if you don’t follow the agreed time. Even if this company still asks you to work, you'd better give up, because the other party already has a bad impression, and your foothold will be worse than others. All companies hate employees who don’t value their time. You must change that.
