J'ai postulé en ligne. Le processus a pris 5 semaines. J'ai passé un entretien chez Coinbase (Toronto, ON) en avr. 2026
Entretien
Many rounds, and then layoffs happened and now my candidacy is in limbo. Overall, it feels like they don't respect your time. Entire process takes over a month it seems.

J'ai passé un entretien chez Coinbase
Entretien
Diving into the technical round, I was presented with a tricky problem about finding a duplicate number in an array. Right away, I felt the pressure; it had to be solved with O(1) space and better than O(n^2) time. The funny part is, I had literally seen this exact question on prachub.com while preparing just days before! The interview also included behavioral questions about teamwork and problem-solving. Overall, it was challenging, but I got the offer in the end, though I decided to decline.
Questions d'entretien [1]
Question 1
Given an array of n+1 integers where each integer is in the range [1, n], find the duplicate number. You must solve it without modifying the array and using O(1) extra space. Time complexity should be better than O(n^2).
Technical Screen, rigorous, 90-minute automated assessment, typically administered via CodeSignal, focusing on practical, multi-part coding problems rather than just abstract LeetCode-style questions. It often involves building functional, real-world components, such as a REST API or an in-memory database with data persistence and edge-case handling.
