Mohit's response identifies a complex problem related to user roles and permissions in a project and mentions the decision to use MongoDB for its flexibility. However, his contribution to the solution is not clearly articulated. He could improve by detailing his specific role in the database design, how he contributed to implementing role-based access control, and his involvement in testing and validation, as described in the benchmark response. Providing more information about his active participation in team collaboration and problem-solving would strengthen his answer.
