The questions
- 01 · Behavioral
Tell me about yourself.
Why interviewers ask this: For a performance marketer, this is your 60-second pitch. The interviewer is screening for clarity, signal, and fit.
How to answer: Use a Past → Present → Future structure: 1 sentence on background, 1–2 on current scope and a relevant win, 1 on why you want this role.
- 02 · Cultural Fit
Why are you interested in this role?
Why interviewers ask this: They are checking that you have read the JD and understand what makes this role and company different from generic alternatives.
How to answer: Tie 2 specific aspects of the role (a project, a stack, a customer segment) to 2 things you have actually done. Avoid flattery.
- 03 · Behavioral
Tell me about a time you failed.
Why interviewers ask this: Interviewers want to see how you handle real situations using the STAR method (Situation, Task, Action, Result).
How to answer: Pick a real failure with measurable consequences. Spend most of the answer on what you learned and the change you made afterward.

How do you set up a creative testing cadence?
Why interviewers ask this: Creative is the dominant performance lever in 2026.

How do you handle iOS attribution post-ATT?
Why interviewers ask this: Tests modern attribution literacy.
