Pros
CQ Roll Call offers great benefits. New employees get three and a half weeks of vacation (and folks who stay longer can get up to 5 or 6 weeks). However, at least for me the annual salary was quite low. Since CQ gets so deep into the weeds of policy, reporters learn how to explain really complex and wonky concepts that competitors often don't. Same goes for legislative procedure.
Cons
It is both a blessing and a curse that CQ Roll Call has existed for nearly 70 years. Blessing in that it has so much institutional knowledge, but curse in that it has failed to adapt to the media changes over that last decade...due in part to pure arrogance among management and a culture that's resistant to change. That's why competitors like Politico, The Hill, etc creamed CQRC over the last several years. And CQRC only started to realize it needed to implement changes in maybe 2011. (Even now, it still hasn't really caught up.)
