How to write a letter to hr manager?

I think you should be personal, you should briefly tell why you deserve this position and name maximum of your qualities and skills that would make you a great employee. Good luck!

What is the position?

If you can, find out the name and title of the person you’re writing to. Introduce yourself and tell what job you’re applying for. Spend a paragraph or two talking about your past experience and why it would make you a good candidate, and why you are interested in this job.

Try not to use the same generic cover letter for every job opening. The point of a cover letter is that you can convey personal information and experience that you can’t put in a resume. This is a good place to express your enthusiasm for the job opening, or good personal qualities that you bring to a job, like a good work ethic or initiative.

Good luck!

Keep your cover letter to 1 page. Human resources will appreciate short, professional letters. You still want your letter to follow the standard business letter format.

A cover letter should include a heading to make it clear which job you’re applying for and, following the introductory paragraph, it can take the form of bullet points or short statements. It should also include your own name, address and contact details.See more details on How to write a covering letter
