London, EnglandPosted Jun 2025 · Candidate report, summarized by Dataford

I interviewed for the Data Scientist role with a mix of coding, then a final interview split into a case study, DS/ML theory, and live coding—overall feeling difficult.

Initial coding assignment — a take-home or starter coding step before scheduling.
Screening call — 30-minute call to discuss fit.
Final interview (2 hours, 3 parts) — case study first, then DS/ML questions for a specific use case, and finally a live coding question.
(General process fit expectation) — culture fit/alignment and technical evaluation were emphasized in the overall flow. Outcome: I didn’t receive an offer, and the takeaway was that the final stage was the hardest and required deep DS/ML understanding for the use case.
