Oura Interview Question Bank
A sample from our database, grouped by round. Sign up to see the full set.
9 of 20 questions shown
Recruiter Screen
1- 1
Τύπος · Motivation
What interests you about Oura's mission and how do you see your skills contributing to our goal of empowering people to understand their bodies?
Coding Screen
3- 2
Τύπος · Data Structures
Given a stream of heart rate data points, design a data structure to efficiently calculate the average heart rate over the last N minutes. Assume N is variable. - 3
Τύπος · Algorithms
Oura tracks sleep stages. Given a sequence of sleep stage labels (e.g., REM, Deep, Light, Awake) and their start times, write a function to calculate the total duration spent in each stage. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Τύπος · API Design
Design an API for Oura users to retrieve their historical sleep data. Consider different time ranges, data granularity (daily, weekly, monthly summaries), and potential pagination for large datasets. - 5
Τύπος · Data Processing Pipeline
Outline a system to process raw sensor data from Oura rings, calculate sleep stages, and store the results for user access. Discuss trade-offs between real-time processing and batch processing. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
Τύπος · Debugging
A user reports that their nightly sleep score is sometimes significantly lower than expected, despite them feeling well-rested. The backend logs show their REM sleep duration is being calculated as zero for several nights. How would you approach debugging this issue? - 7
Τύπος · Algorithm - Hard
Implement a function that takes a user's daily activity data (e.g., steps, active minutes) and sleep data (e.g., sleep duration, time in bed) and predicts a 'readiness' score from 0-100. You can define the factors and their weighting, but the logic should be defensible. - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
10- 8
Τύπος · Conflict Resolution
Tell me about a time you had a significant disagreement with a cross-functional team member (e.g., engineer, designer, marketer). How did you approach the situation and what was the outcome? - 9
Τύπος · Ownership
Tell me about a time you took initiative to solve a problem that wasn't explicitly part of your job description. What was the situation, and what was the outcome? - + 8 more questions in this round (sign up to unlock)
