First, there was a 30-minute interview with HR. She asked me some general questions about my background and how much I knew about the company.
The next step, which was three or four days after the first interview, was a code assignment challenge that I could not pass.
Code assignment: They asked me to create a web server with three math APIs (e.g., Fibonacci, etc.). I was also asked to log the runtime of these APIs. I received feedback on my code, stating that the logger I implemented was inefficient and too simple. However, when I received the code assignment, I asked about their expectations for the logger implementation. I specifically inquired if a simple, custom logger would be acceptable or if there were other requirements. They confirmed that I could write a custom one.
