After yesterday's interview, I got a call from the head office today, and then I waited for the notice? Sharp meaning?

This situation is mostly due to internal communication of the head office. Maybe the recruitment quota has changed. If so, you should not be informed to go to the interview for the time being.

Another possibility is that the target needs further screening. If so, it is estimated that a series of people will be screened again, and a certain number of interviewers will be cut off for the first interview after screening. In this case, you still have a chance.

Generally speaking, don't worry too much. Man proposes, God disposes. Just don't care too much. Relax ~

I hope I can dispel your concerns, help you, and hope to adopt it.
