Varun's response provides a detailed account of his experience with Agile and Scrum methodologies, particularly in managing backlogs and facilitating stakeholder sign-offs. He gives a concrete example from the HVAC domain, explaining the process of breaking down modules, prioritizing user stories, and conducting sprint meetings. However, Varun could improve by clearly stating the outcomes of these processes and how they contributed to the success of the project. Additionally, he could mention any specific challenges he faced and how he addressed them to demonstrate problem-solving skills.
