The interviewer will generally make a comprehensive evaluation of the job seeker's interview. B can be a signal representing a score. If I were you, I would divide it into A, B and C files. In fact, you don't have to be discouraged. If English letters are really used to express the evaluation, B file may not have no chance, because often excellent A file candidates may not adapt to the needs of enterprises, and too excellent talents are often the goals of other enterprises.

I'll teach you a little trick when I hear from you. If you know the interviewer's last name and the other person's direct phone number, you might as well give him a call in a week or so, mainly to thank him for giving you an interview and for learning a lot from this interview. If the other person is still hesitating and considering, your thank-you call will give the interviewer a new understanding of you.

Of course, thanks are the main thing. If the other person doesn't mention it, don't ask the interview result, otherwise it may be counterproductive.
