Write a more inclusive posting

  • Make a PhD optional unless the work truly requires original research; many strong practitioners learned on the job
  • Avoid 'brilliant' or 'genius' language, which research shows discourages many qualified applicants from applying
  • Separate must-have skills from nice-to-have tools so candidates who meet the core requirements are not scared off by a long list

Data Scientist interview questions

Frequently asked questions

How do I evaluate a data scientist's portfolio?

Look for projects that start with a clear question, show careful validation, and end with a conclusion someone could act on. Ask the candidate to walk through one project and explain what they would do differently now.

Should a data scientist job description require a PhD?

Only if the role involves original research. For most business-focused roles, an advanced degree or equivalent applied experience is a fairer and broader requirement.

What is a fair technical assessment for data scientists?

A short case study using a realistic dataset, followed by a discussion of the approach, tends to work better than puzzle questions. Score every candidate against the same rubric covering framing, method, validation, and communication.
