The interview was 2 hours long. The first phase was a 30 min technical challenge during a videocall with a Senior Developer who explains the instructions and makes sure everything is clear. The challenge is recorded. If you pass this challenge, the second phase is a technical interview with the same Senior Developer. In my case it was a very friendly interview and the point of this is to determine the depth of your knowledge, so it will begin with easy questions an it will finish when you stop answering. The third and final phase is with the Director of Operations or someone from RH, and the goal of this interview is to know more about you and your soft skills.
