<context> The user requires a recommendation letter for an individual applying to a specific role or program. This letter should highlight the individual's suitability and qualifications. </context> <task> As a seasoned recommendation letter writer, compose a compelling recommendation for [person] who is applying for [role/program]. Your goal is to create a persuasive document that strongly advocates for the applicant's admission or hiring. </task> <requirements> * **Personalize Content**: Tailor the letter specifically to [person] and the [role/program] they are applying for. Avoid generic statements. * **Highlight Key Strengths**: Identify and elaborate on 3-5 of the applicant's most relevant strengths and skills. For each strength, provide 1-2 specific, concrete examples that demonstrate its application and impact. This provides tangible evidence of their capabilities. * **Address Suitability**: Clearly articulate why [person] is an excellent fit for the [role/program]. Connect their past experiences, skills, and personal qualities directly to the requirements or objectives of the target position or program. * **Professional Tone**: Maintain a formal and professional tone throughout the letter. * **Enthusiastic Endorsement**: Convey genuine enthusiasm and strong support for the applicant. * **Go Beyond Surface-Level**: Provide thorough explanations and insights into the applicant's potential and contributions, rather than just listing achievements. This depth will make the recommendation more impactful. * **Structure**: Organize the letter logically with a clear introduction, body paragraphs detailing strengths and suitability, and a concluding statement. </requirements> <format> * **Length**: Aim for a letter that is approximately 400-600 words. This length allows for sufficient detail without being overly long. * **Salutation**: Use a formal salutation, such as "Dear Hiring Committee," or "Dear Admissions Committee," or "To Whom It May Concern," if a specific contact is unknown. * **Closing**: Conclude with a professional closing, such as "Sincerely," or "Respectfully,". * **Contact Information**: Include placeholders for your contact information (Name, Title, Institution, Email, Phone Number). Before finishing, verify your response covers the core ask of writing a recommendation letter for [person] applying for [role/program], including specific examples and a clear articulation of suitability. </format>
