I applied online. The process took 2 weeks. I interviewed at Comcast (New York, NY) in Mar 2017
Interview
I summited my résumé online, I emailed the hiring manager. Surprisingly he answered within the next few days. He asked transcript. Within the next few days he schedule a phone interview.
4 questions about your past experiences, your tech knowledge, and your interests. It was very quick and brief. Involved no practicals or multiple choice questions. Allows multiple tries and to look back at your questions.
The interview was pretty easy as long as you are prepared. The first interview will be a video interview and if you make it pass that part you will have someone reach out to you in a few days for a phone interview
