Should I write an appreciation letter after being accepted into position?
This is not expected of you, and most people would not do it. I don’t see anything wrong with it, as long as your letter is professional and businesslike. Basically, thank you for this opportunity, etc. Short and sweet, this letter should be a brief paragraph only and should not get emotional nor should it go into detail about your personal history or that sort of thing. If done correctly, this letter will give an impression that you are a very polite and motivated person. If done incorrectly, you could look unstable, lol.
