Writing this in hopes of helping someone find the information that I failed to find. First step was applying online. Within the first week I was contacted by a recruiter to set up a phone interview, which was a few days later. The phone interview consisted of some basic background questions in relation to the job which you are applying for. The recruiter told me directly on the phone that she would be sending me to the next round of interviews ( in person) which was almost two weeks later. I interviewed with two people and from what I gather these two are closer to whom you will be directly working with/for. A majority of questions were from a piece of paper that each interviewer had. ( Tip- do the best you can to answer each question in depth and remember that it is ok to have them repeat the question or ask if that was a thorough enough answer). The 3rd and final interview with with a total of four interviewers. This was pretty much the same concept as the 2nd interview with asking questions from a sheet as well as individual questions to get a feel for your personality. In all it took about 5-6 weeks for the entire process.
My advice- be confident and patient. The process is long and can make you feel defeated at times but Comcast is doing a thorough process of making sure they pick the right candidate. Look sharp for your and be relaxed for your interviews. I really do hope this helps someone! Good Luck!
