Eight Sleep interview questions

Had several rounds with people from various functions, and overall the conversations were thoughtful and engaging. Most of the earlier interviews focused on conceptual thinking, modeling approaches, and communication/problem-solving style. The final stage involved a take-home exercise and presentation, which was worthwhile and relevant to the role. During the presentation, interviewers added comments and questions directly into the document in real time, which made parts of the discussion slightly more difficult to navigate. There was also a strong emphasis on live Python coding and algorithm-style questions, so candidates should be prepared to demonstrate coding fluency under time pressure in addition to conceptual data science knowledge. Overall, the process was organized and communication was responsive throughout. However, I found parts of a post-interview feedback conversation relatively brief and quite direct in tone, and it did not provide much specificity around the evaluation or how the decision was made. While I appreciated the opportunity to discuss it, I would have valued more concrete feedback on areas of mismatch between the role requirements and my performance.

Combinedew process itself is fairly standard, but there are a few things worth flagging for candidates considering applying. First, the design task asks you to redesign their own product — which is widely considered poor practice in product design interviews, since it puts candidates in an awkward position and doesn't allow for a fair, neutral assessment. My approach to the task was grounded and realistic: I worked from known facts and proposed changes that were genuinely feasible. The feedback suggested they were looking for something more speculative and high-concept — a "wow" hypothesis rather than a well-reasoned proposal. That's a legitimate difference in philosophy, and I respect that. What's harder to overlook is that after I was rejected at the task stage (second to last round), several of my suggestions appeared in their product. Could be a coincidence, but it doesn't leave a great impression. It also feels worth mentioning that the role has been open for nearly a year. Combined with everything above, it's hard to shake the feeling that the process isn't entirely genuine — whether they are actively hiring or simply using the interview cycle for other purposes.
