For engineering graduates, GD themes typically center on current affairs and industry trends. Recruiters often pick topics that relate to government initiatives, technology developments, or social issues affecting the sector. Examples might include (but are not limited to) government programs (like Make in India, Digital India, GST reforms), technology trends (AI/automation in manufacturing, Industry 4.0, renewable energy), and environmental or socio-economic issues (climate change initiatives, sustainability goals, infrastructure projects).
