What Data Scientist interviewers listen for

• ✓ Specific examples with measurable outcomes, not general statements
• ✓ Role-specific technical vocabulary used naturally, not forced
• ✓ Confident pace — 110–140 words per minute, no long silences
• ✓ Structured answers: situation → action → result
• ✓ Direct eye contact with the camera, not the screen

Common mistakes in Data Scientist video interviews

• ✗ Answering too broadly — not tying examples to Data Scientist-specific situations
• ✗ Overusing filler words (um, uh, like) — signals nervousness
• ✗ Looking at your own video feed instead of the camera
• ✗ Answers over 3 minutes — most interviewers tune out after 90 seconds
• ✗ Missing role vocabulary that ATS pre-screens for in async video tools
