Cisco Software Developer interview questions

Calm and serene interviewer, supportive and asked more about my projects mentioned in my resume. I was asked about one of my projects and the questions were more on how I approached the whole process and not the tech itself. Then he asked me a simple puzzle. He then moved on to ask which was my favorite language.

It consisted of the aptitude-coding test: Aptitute and logical reasoning, coding came from the concept of graphs, followed by technical, Managerial, and HR round. With proper preparation, it can be cleared. Thank You
