Culture
Ambitious, detail-oriented, client-obsessed. Described as 'dynamic, demanding, and supportive.' High bar for ownership; interns are treated as mini-operators, not order-takers.
Is This Role For You?
- You're wrapping up a Grande École (HEC, ESCP, Skema, etc.) or equivalent Bac+4/5 and want real operational exposure—not coffee runs
- You're energized by ambiguity: managing multiple client relationships, timelines, and stakeholder expectations simultaneously
- You have strong fundamentals: Excel modeling, clear writing, structured thinking, and the ability to synthesize complex information for clients
- You're genuinely curious about how ad tech, marketing operations, and consulting revenue models actually work
- You want a foot in the door at a world-class agency with clear upgrade path to full-time
- You're looking for a low-pressure summer gig; this is a real job with accountability, client-facing pressure, and high execution standards
- You're weak on self-direction or detail work; operations is 80% unglamorous process optimization and follow-through
- You don't actually care about marketing or business; you just need any internship to tick a box
Interview Process
Initial Screening
HR phone screen: confirm your background, motivation, availability (6 months), and fluency with Excel/PowerPoint
Case Study / Exercise
Small take-home: organize fictional client project details into a staffing plan and budget tracker (tests Excel + structured thinking)
Director Interview
Deep dive with Activation Marketing Director: discuss your understanding of agency operations, client management philosophy, and what you want to learn
Senior Manager Panel
Conversation with 1-2 senior managers who'll collaborate with you; they assess fit, maturity, and ability to handle ambiguity
