Tell me about a time you were given a vague goal and had to define the work yourself.

How to answer this behavioral interview question: a complete STAR example, the mistakes interviewers watch for, and the follow-ups you should expect.

A strong STAR example answer

Our leadership asked my team to "improve customer engagement" with no metric, no deadline, and no defined scope. It was a one-line mandate in a quarterly planning doc, and nobody owned it.

Rather than wait for clarity that was not coming, I spent the first week interviewing eight customer success managers and pulling three months of usage data. I found that accounts with weekly logins under two had a 40 percent higher churn risk, so I proposed redefining the goal as raising weekly active usage among at-risk accounts. I wrote a one-page brief with that definition, a target metric, and three candidate initiatives, then got my manager and the support lead to sign off on it.

We shipped the top initiative, an in-app checklist for new accounts, in five weeks. Weekly active usage in the target segment rose from 31 to 46 percent over the next quarter, and churn in that cohort dropped by about a fifth.

Writing the brief was the turning point — once the goal was on paper, alignment was easy.

How to structure your own answer

• Situation: Describe the vague directive you received and why it was undefined.
• Task: Clarify what you decided you were actually responsible for.
• Action: Explain how you scoped the problem, validated assumptions, and got alignment.
• Result: Share the outcome and what it taught you about creating clarity.

Common mistakes to avoid

• Complaining about the vague goal instead of showing how you created structure around it.
• Jumping straight to solutions without showing how you validated the real problem first.
• Skipping the alignment step — defining the work alone and never checking with stakeholders.
• Ending without a measurable result, which leaves the interviewer unsure anything shipped.

Follow-up questions to prepare for

Interviewers use follow-ups to verify your story is real. If you use this question in a real interview, expect probes like:

• What would you have done if your manager rejected your proposed definition?
• How did you decide which of the three candidate initiatives to build first?
• How do you handle ambiguity when you have no data to guide you?
