Pros
One could find far worse jobs, no doubt - but one could also find a far better job. It was very "meh" after the honeymoon period for me. For awhile one could approach the job from an "engineer" perspective and get down and dirty with how the Internet works (HFC and Fiber) or some aspects of VoIP. If you got lucky with the schedule lottery you could maybe work four ten-hour shifts and get an extra day away from there; I'd say that is a "pro" if you like three days off a week and don't mind the extra couple hours on the work days. This was the type of job that doesn't follow you out the door, so you don't have to do anything outside of the defined schedule - very easy to leave the frustrations of the job on the desk (though those frustrations will be waiting for you when you get back to that desk, ready to pounce and devour the bits of your soul that managed to hide for as long as they could, standing over you with the blood still squirting from your still-beating-heart it grips in its jaws before administering the death knell). Moving from a bowels-of-hell Comcast Tier 1 tech support role into this department was a godsend, but that's just because B seems like paradise going from (A) -> B when A is unparalleled in sheer awfulness (seriously... it's incredible how emboldened people become when they have a post to whip in the form of a human making a low wage on the other end of a phone line); it doesn't matter if B is just another piece of garbage in the dump when A is a turd on a piece of garbage in a dump that inexplicably has been a raging inferno for a decade and A is where you spend your days. As with so many jobs that kind of suck or seriously suck (this one just kind of sucked but then started to seriously suck during the transition to supporting Managed Services in early 2019), one may find great camaraderie with their fellow downtrodden proletariat workers; call it "trauma-bonding".
Cons
No matter how much Comcast says things like "Jimmy here started in customer service twenty years ago and now he is a product analyst, yay Jimmy!" to illustrate all the "career opportunities", it is very unlikely starting in a customer support role will yield any sort of meaningful transition to a less crappy role with a raise that is noticeable in the pocket book. The groups above support look at support groups as i-d-i-o-ts - otherwise they wouldn't be in support, right? Right. That's why you can work the garbage jobs here, get tuition reimbursement and earn a degree, be qualified for a much better position, apply to all sorts of jobs where your new degree is a qualification (not to mention any domain knowledge you have from working there for a few years), and never get an interview. For an individual like myself that was very interested in exiting awful customer service/phone support jobs and entering the technology world it seemed like a dream to go to an "engineer" position; it didn't take long to realize that the word "engineer" was used in an EXTREMELY liberal way to describe the Enterprise Technical Support (ETS) "Engineer" role. It is really just glorified Tier 1 customer support. However, as mentioned, one could approach it with an actual engineer mindset and make the best of what tech we could actually touch. (Side-note: the more a coworker says "I AM THE ENGINEER" when talking to customers or Tier 1 agents the less likely it is that the individual approaches the job as an engineer and instead is just some p-r-i-c-k that knows next to nothing). I will never forget being strung along making it seem like I had a shot at a promotion or even moving to my goal of doing more software-development-oriented work in the department only to overhear a manager interviewing someone... for the job they dangled in front of me for several months. I suppose it could be considered a "pro" though because that slap in the face and feeling of stupidity inspired action and resolve to never be played like that again (at least professionally... we are all but fools when caught in the throes of romance, are we not? That's a different story, where do I give reviews on that?). The transition from supporting Fiber, VoIP, etcetera, into Managed Services took the job from "not great, not awful, kind of technical if you want to be technical but you can never get that deep in the tech" to "oh my god, I can't believe my job is to call Taco Bell and convince some t-u-r-d of a teenaged manager that I am not conducting a social engineering attack by calling and saying I am with Comcast and we manage your IT and your modem is offline" or "oh my god I can't believe I am on hold with Verizon to ask what is wrong with this Chikfila's DSL Internet". For those of you left behind... godspeed. This was a department that was very big on the ol' brown-nosing thing; show up, say "yes", make your numbers look good at all costs... you will zip right to the top! I hear that's just the world in general though.
