Cisco Software Engineer interview questions

I was emailed regarding an opportunity and I emailed back. Following this, I had a call, and then the manager asked me specific questions regarding my background. After answering these questions, I said thank you and moved on. 3 weeks later I was contacted again and surprisingly they were interested in me, hurray! I continued along the process and did a lot of eating and chilling, and all of a sudden I was good to go.
