First 30 minutes was an interview with their head of the Department. First, it was like any interview where he asked me questions, such as "tell me about a time you worked on a team. Did it go well? What things could you have done differently to make it better?" He then asked actual accounting questions, such as "when would you defer a revenue rather than recognize it right away?" and "why would you capitalize an asset rather than expense it?"
Overall, half of the interview was situational and more based on my personality while the remaining 15 minutes was testing my accounting knowledge.
Then, he asked if I had extra time to consult with another employee whom he brought along. She asked basically the same questions, and he said they would later compare answers.
