Comcast Device Certification Engineer interview questions

I applied online. I was given a call in 3-4 weeks to schedule a phone interview with the manager. On the scheduled time, the manager called and explained mostly about the job and what they're looking for. Based on my experience and knowledge, the job was perfectly suited for me. He even told me I have been the best candidate till now. I was expecting a positive reponse. But did not get to the next round.
