I applied in-person. The process took 3 weeks. I interviewed at Comcast (Indianapolis, IN) in Nov 2017
Interview
Meet with Dept. Supervisor and another area Manager. Asked general questions about knowledge base and decision making scenarios. Pretty standard really. They seem more concerned with how you plan to handle certain situations than what you know about the work itself. Seems to be a consensus that they can train you on that, but they don't want to try and change your personality.
