There are a number of different kinds to choose from, and the greeting you choose will depend on how much information you have about the company.
If you know the name of the hiring manager, your salutation should be something like "Dear [insert name]" followed by either a comma or a colon. Make sure to address the manager formally using their proper title (Mr., Ms., Dr., etc.).
If you don't know the name of the hiring manager, consider addressing your letter "Dear Hiring Manager," "Dear Recruiting Team," or "Dear [insert company name] Team."
As a last resort, address the letter "To whom it may concern," though we recommend avoiding this salutation, as it could come across as a template letter.
We take blue collar / Working class staff recruitment only if it is with large project, which includes sourcing of critical / Senior / Engineering positions.
