Call load - Sometimes the calls are back to back for 8 hours and sometimes there will be a 30 minute wait between each call.
Management - Your experience at SDC depends heavily on the supervisor you are assigned. these will rotate frequently. One of the best supervisors I have ever worked for was at SDC, and when they rotated, I'd go as far as saying my next supervisor was one of the worst and this absolutely did impact my choice to leave the company.
Comcast tenant - I worked in the Comcast tenant. The Quality Assurance method was a serious problem. Most agents were in a perpetual state of failing QA completely with less than 50% compliance due completely to how cryptic and purposeless the QA method was. I believe this opinion reflects the opinion of many other agents at SDC as I have discusses this matter at length. Depending on your supervisor, your experience with QA may border on harassment. Comcast's customers are often rightfully angry. You will deal with absolutely unreasonable customers all day long as a result of Comcast's total incompetence.
WITH THAT SAID:
This is still truly a fantastic opportunity if you need money. Go into it with the right mindset and tolerate fundamental flaws for as long as you can. I gave this a thumbs up for the 6 month business outlook because 6 months is right about the amount of time that I believe this job will stay tolerable for most.
