To prepare for a performance review, begin by listing your accomplishments over the review period, particularly noting any that had a measurable impact on the team or company. Identify areas where you've grown and any skills you've developed, as well as potential areas for improvement. Think about your future goals and how they align with the company’s direction; this shows you’re proactive about growth. Practice a concise summary of your key points to make the discussion smoother. By preparing specific examples and setting clear, aligned goals, you can make a strong, positive impression in your performance review.
