The foreign company tried for 4 days without notice.

You can try to contact the recruiter actively and ask about the interview results.

If you don't receive the notice to provide an interview for four days, if the interview is good, usually on the second or third day, the human resources department will take the initiative to communicate with them to confirm whether they are willing to accept their position. This is a common practice in order to identify candidates as soon as possible. In another case, the interview process is not over yet, and the recruiter is still interviewing and comparing with other applicants. In this case, standardized large enterprises will generally give the next step within 7 days, such as entering the next round of interviews or waiting for the final decision. This is to ensure a fair and comprehensive evaluation of the performance of all candidates. During the recruitment process, the position will change or other changes will occur. This will cause recruiters to need more time to make a decision or re-evaluate candidates. If you really want to know the interview results, you can take the initiative to contact the human resources department and politely ask them if there is any update about the interview results.
