One of the biggest concerns job applicants have is answering the “Tell me about yourself” question. In some interviews, even if you survive this question and land the job, you may get caught in another “tell me about yourself” trap with a self-assessment. Self-assessments are documents written by the employee discussing his or her contributions and shortcomings over the course of a period of time (such as quarter or a year), and a well-written, accurate one can boost your career.
Gather examples of your work and gather information related to your work (such as emails and memos). Review your job description (if you were given one) and look for what your goals or crucial functions are at your job.
Paraphrase the critical functions and goals of your job as you write your self-assessment. According to usuhs.mil, this helps organize your thoughts and helps to give your manager a clear idea of how you understood your job duties.
Write about your most significant achievements. According to usuhs.mil, self-assessments should not be lengthy; pick out your critical accomplishments and write about those.
Explain how your actions in a given situation benefited the organization. For example, it is not enough to say that you increased revenue by 10 percent; go on to explain the results of that increase (such as increased positive exposure in the marketplace and new benchmarks for the company).
Detail any challenges you encountered, what you learned from them and/or how you overcame them.
Be specific with your examples and use clear and concise language to write your report.
