If you have been for an interview and want to say thank you then this is a nice thing to do which also reminds the employer that they interviewed you and gets your skills and attributes back in the forefront of their mind.
Try to write your letter and refer to some of what you discussed in the interview so that they know that you listened and what parts you took on board. Make them relevant to the role rather than specifically about the company.
If you are looking at how best to write your follow up letter following an interview, please see the below example which you can use as a guide.
