Advice
3. First Paragraph, Content and last line
In your first paragraph, make the reason you're writing clear and sell yourself; writing what makes you better than others straight off; ensure the letter shows how motivated and enthusiastic you are. Do not include negative comments. Try to use dynamic verbs for each skill you are explaining, such as; Research, Analysed, clarified; People skills - Collaborated, communicated
Finish with a comment about how enthusiastic you are to hear back from them and stating the best time that they can contact you for a meeting or interview.
