1. Resume mismatch: when HR reads the resume, it finds that the work experience and skills described in the resume do not match the position recruited, or HR thinks that the candidate is not competitive enough, so it will mark the resume as pending.

2. Too many resumes: If the enterprise receives a large number of resumes, HR will give priority to screening resumes that meet the requirements, and those that do not meet the requirements will be marked as pending, and then checked if necessary.
