Full Interview Process Breakdown

Media Master Program (2024 process)

According to a 2024 successful hire, the interview has two stages:

Stage 1: HR video interview (about 15 minutes, in Mandarin)

After passing the resume screen, HR sends a scheduling link. Questions include:

• Self-introduction
• Why do you want to join this program?
• Describe a setback and what you learned from it
• Teamwork experience

Stage 2: On-site interview (about 3 hours or more)

Divided into three parts:

A. Company introduction (20 minutes) HR and the GM introduce the company culture, with drinks and snacks during the break.

B. Case analysis (group discussion) Groups of about 5, each given 3 sheets of poster paper and colored markers. The prompt is shown on a projector, for example: "You have a NT$1M budget to promote a new company's product line. How would you allocate it? What results would you expect?" 30 minutes of discussion + a 5-minute presentation. Managers observe from the side and take notes on every speaker.

C. Panel Interview The same group faces about 5 managers, each asking one question that everyone answers in turn:

1. Self-introduction
2. Teamwork: how do you put the right person in the right position?
3. What is your vision for the media industry?
4. Which department do you most want to join, and why?
5. What unique strength makes us have to hire you?

Insider Experience

Interview preparation tips

• The case analysis is key: Candidates without a media/advertising background are at a disadvantage in the case discussion, so learn the basics of media buying beforehand
• The interview is entirely in Mandarin: GroupM doesn't require you to show off English, but the ability to read English material still matters
• Showing enthusiasm matters more than expertise: Several candidates stressed that curiosity and a willingness to learn about the media industry are valued more than existing skills
• For data-related roles: If you have no hands-on experience with Power BI or Tableau, build a few demo pieces to bring to the interview
• Prepare concrete cases: Senior roles get asked "What's the best ad campaign you've worked on?" so you need concrete data to back it up

Work culture

• The rotation system lets newcomers explore different departments
• The pace can be very fast ("pretty grueling")
• After building experience, you can move to a brand-side marketing department

Who This Job Suits

Ideal traits

• Curiosity about the media industry: The interview requires showing your interest in and observations of media trends and digital advertising
• Cross-disciplinary communication: Candidates come from diverse majors, so interacting with people from different backgrounds during teamwork matters
• Creative thinking: The case analysis asks you to propose a creative media buying strategy within a limited time
• Data sensitivity: The AI Fellowship places special weight on data analysis and the application of AI tools
• Eagerness to learn: GroupM offers WPP's full global training resources, so those willing to keep learning benefit most

Who may not be a fit

• People expecting high pay: Media agency entry salaries are on the low side (about NT$28K), so you rely on promotions and job changes to grow
• People who dislike a fast pace: The media industry is fast, deadlines are tight, and overtime is the norm
• People who only want a single job: The rotation system means you may be assigned to a department that wasn't your first choice
