Mohit's response indicates that he has experience with responsive design, mentioning the use of flexbox and Bootstrap in his TextUtils project. However, his explanation is somewhat vague and lacks the structured detail of the benchmark response. He could improve by providing specific examples of how he used Bootstrap's grid system and responsive classes, as well as discussing the mobile-first approach in more depth. Additionally, his comment on security issues with Bootstrap is unsubstantiated and could benefit from clarification or omission to maintain focus on the positive aspects of his experience.
