Fetch Rewards·Data Scientist·Technical Phone Screen

Fetch Rewards data scientist interview, one round, ambiguous problem with two interviewers who barely said a word the whole time. The whole thing felt like a test of whether you'd panic or just keep moving.
- You have 45 minutes, two interviewers who give you almost nothing, and a vague problem. How do you open the session to set a clear agenda, confirm what decision the analysis is meant to support, and propose a success metric with guardrails?
- When interviewers are unresponsive, how do you handle logging your assumptions so they're visible, and how do you push for confirmation without it becoming awkward?
- If the interviewer asks for an 'average' but you think the right approach is to compute totals first and then derive ratios, how do you handle that disagreement without losing momentum or annoying them?
- Describe how you would structure two explicit checkpoints during the interview (say, around the 10-minute and 30-minute marks) and what you do if the interviewers stay silent at both.
- How do you close out the session: summarizing your findings, surfacing risks, proposing next steps, and explicitly asking for alignment on your conclusion?
