Reflective storytelling helps articulate personal journeys, motivations, and learning experiences, making responses more relatable and engaging to interviewers. This technique can effectively showcase qualities like resilience, adaptability, and leadership. Furthermore, personal anecdotes can differentiate candidates in a competitive environment, adding a human touch to their narrative. Ultimately, engaging storytelling enhances communication skills and helps candidates leave a memorable impression during their interviews.
