I am a recruiter, and the possibilities are: 1. You have something that doesn't meet their needs, but they can't find the right one for a while and will measure it several times; 2, resume is too big, recruiters will forget who you are and read it several times ... 3, many employers themselves are not formal, and it is common for a position to hang for a year or two, because it can't be used after paying the money; 4, recruiters, responsible leaders, many people may have seen it once. If you like this company very much, I suggest you take the initiative to call and ask. There are many reasons, so don't guess too much.
