To effectively follow oral instructions for composing a cover letter for a job application, the following step would be the most beneficial:
Take Notes While Listening: Actively jot down key points, requirements, and specific details mentioned in the oral instructions. This helps ensure you capture all important aspects, such as formatting, content to include (like experiences or skills), the tone to adopt, and any specific points that need to be addressed in your cover letter.
Additionally, it can be helpful to ask clarifying questions if you're unsure about any part of the instructions, ensuring that you fully understand what is expected before you begin writing.
