I had a technical round where they asked questions about object oriented programming. I had it in Python, where the requiters showed me some code and I had to explain how to change it to make it better.

They posted the job in July, and I immediately applied for it. I got a response three months later (in September) with a case study assessment that had to be delivered within a week. After another three months (at the end of November), I passed the case study assessment and secured a 90-minute interview to discuss my solution. The interview itself did not follow a specific process. They asked me about my background and the projects I had worked on, as well as the technologies I had used. After that, they had me present my solution for the case study and asked a few questions about it.
