How long will it take for the HR director to join the company after the interview?

Generally, after the interview, companies that are in a hurry to recruit may notify to confirm whether they can arrive at their posts that afternoon, and many will notify them the next day. There are more people in the interview, so it needs to be screened. If you don't inform me the next day or later, it's not appropriate. After the interview is passed, it is usually next Monday. If there are more candidates, it is convenient to make unified arrangements. If the interview is earlier, you may be told to join this week.
