I had a very bad experience working for Comcast. Endless pointless meetings, long swaths of time were there was no work assigned to me and asking for work was an ordeal, odious and micromanaging scrum masters, out of touch execs, doomed projects, constant team reshuffling, incompetent, rude coworkers... I'd highly recommend avoiding if you are a talented software engineer and especially if you are looking for your first or second dev job and don't really know how to assess the environment. From my vantage point if was BAD - stay away!
