Answer core behavioral questions for data roles

You are interviewing directly with a hiring manager who is known to be very selective. The interview is entirely behavioral (BQ).

Prepare structured answers (2–4 minutes each) to the following prompts. Use the STAR framework (Situation, Task, Action, Result) and include specific metrics.

1. Tell me about a project you solved using data.
   • What was the business problem?
   • What data did you use and why?
   • What analysis/modeling did you do?
   • What decision changed because of your work?
2. Tell me about a project that made impact.
   • Define impact (revenue, cost, risk, user growth, process time, SLA, etc.).
   • Explain your role vs. the team’s role.
3. Have you faced issues with data quality?
   • Describe the issue type(s): missingness, duplicates, inconsistent definitions, late arriving data, broken pipelines, label errors, etc.
   • How did you detect, quantify, and fix/mitigate it?
   • What preventative controls did you implement?
4. Why are you changing from finance to data?
   • What motivated the shift?
   • What transferable skills do you bring?
   • What proof do you have (projects, results, coursework, tooling) that you can perform in the new role?

Deliverables:

• For each prompt, provide an outline and a final polished spoken answer.
• Include 1–2 follow-up questions the interviewer might ask and how you would respond.
