Why interviewers ask this question

This question reveals your values and motivations more directly than most interview questions. It tells the interviewer whether you are primarily driven by external metrics (revenue, title, salary), by craft (doing excellent work), by impact on others, or by learning and growth. Interviewers use the answer to assess cultural fit — a company that values team success over individual achievement will be wary of a candidate whose success definition is entirely personal. A results-focused sales organisation will be wary of a candidate whose success definition has no measurable component.

How to structure your answer

Give a specific and genuine definition, connect it to an example of a time you felt successful in this way, and then connect it to what you are looking for in this role.

Strong example answer: "Success for me means delivering something that people genuinely use and that makes their work easier — not just something that ships and gets forgotten. In my last role, the metric I cared most about was whether the product had daily active users six months after launch, not whether we hit the launch date. [Example:] We shipped a reporting tool that the product team had been wanting for two years. Three months after launch, usage was higher than any internal tool we'd built before. That felt like success — not the launch itself. In this role, I would define success in the first year as building relationships with enough internal stakeholders that I can get things prioritised and shipped faster than I could in year one at my last company."

What to avoid

Do not give a success definition that is entirely generic ("I feel successful when I achieve my goals and help the team"). Do not give a definition that sounds purely self-serving ("Success means getting promoted quickly and maximising my earning potential") — even if partially true, it raises questions about what happens when the interests of the role and your personal advancement diverge. Do not give a definition that has no connection to the role or company you are interviewing with.

Aligning your answer with the company

Read the company's mission, values, and recent press before the interview. If the company explicitly values customer impact, connect your success definition to how customers were affected. If the company values innovation, connect it to how you pushed into new territory. The goal is not to be sycophantic but to show genuine alignment: your honest success definition maps naturally to what this role and company offer.

Frequently asked questions

Can I mention financial success or career advancement?
Yes, if honest, and if you balance it with other dimensions. "I define success partly through financial progression — I want the compensation I earn to reflect the value I create — but I also need to feel that the work I am doing matters beyond the number" is honest and multidimensional. Purely financial success definitions read as shallow; balanced answers that include financial progression alongside impact or craft read as mature and realistic.
Should I ask what success looks like in this role?
Absolutely, either at the end of your answer or as a natural follow-on to the discussion. "That's how I think about success generally — I'd love to know how you would define success in this role for someone in the first six months" turns the conversation into a dialogue and gives you information you genuinely need.
