Is This Role For You?
- You're a final-year commerce, business school, or marketing/e-commerce master's student hungry to ship real campaigns
- You live and breathe Google Analytics, Google Ads, SEO metrics—and actually enjoy spreadsheets
- You can juggle multiple stakeholders (internal teams, merchandising, SEM/SEO experts) and keep everyone aligned
- You're creative but rigorous: equal parts data skeptic and trend scout
- You need a 9-to-5 remote setup or flexibility; this is on-site, full-time internship
- You're not comfortable making decisions based on numbers or diving into campaign performance daily
- You expect heavy mentorship in basic digital marketing concepts; this role assumes working knowledge of SEO/SEA fundamentals
