I found a job at home through my relationship and asked me to call the manager of the company's human resources department directly. What should I say?

First; Know clearly the last name, rank and responsibility of the person you want to call in the company, and determine their authority.

Second; Explain your purpose, because someone recommended you to interview for a position, a job. If you are not sure which department you want to go to, tell me your advantages and hope to join your company.

Third; Determine the deadline for reply and the subsequent schedule.
