Applied online. Received a questionnaire asking about my background and interests. The second step was a technical phone screen with an engineer from the team that was hiring. It was a quite simple problem that asked to implement a more specialized data structure using basic data structures. The third and final step was a remote onsite about 3 hours. There were 2 engineers interviewing. The task was to implement a specialized database. The first hour was spent on discussing the design and how I would approach the problem. Then 2 hours was spent on me screen sharing and coding the solution out. I was also allowed to use everything online etc. Overall okayish experience. But there was no feedback on what I did good and what I should have improved. Also, no time for questions and interviews focused only on technical skills. I wonder what does it tell about the culture?
