I applied through an employee referral. The process took 2 weeks. I interviewed at Comcast in Apr 2014
Interview
I filled out the application mid March. A week later I received an email to complete an assessment and the next day I had a phone interview. A week later I attended the GIS and had a second interview with a Comcast Manager. The questions were slightly different from the phone interview.
