The general process is:
1, recommended by internal staff, will recommend resumes to business recruiters in the internal system.
2. Under normal circumstances, hr will simply check whether it meets the requirements after getting the resume.
3. If it meets the requirements, it will forward the resume to the business team, such as the team leader or colleagues interviewed in the group.
4. If yes, colleagues of the group or hr will contact the candidate for an interview.
The introduction needs to go to the HR department, but if you have already gone to the project leader, you will make an appointment for an interview soon, which is basically a one-time interview.
