Need Urgent Help: How Do I Write a Confirmation Letter for a Project Engineer?

Hello,

Could you please provide me with a sample letter of confirmation of appointment for a project engineer?

Please treat this as urgent.

Thank you.

Hi, I am working in a pharmaceutical company. I have completed my probation period and now wish to request a confirmation letter from my Head Office. Could you please provide guidance on how to write this request? Can you also provide a sample format? Thank you in advance.
