Vantaggi
The best thing I can say is that most coworkers at the individual contributor level, and first-level managers who had worked their way up over time from the roles they were now managing, were very good and I have great respect for their skills, values, and work ethic. There are always exceptions to this of course, but they were the minority.
Svantaggi
On the field side, work/life balance is not satisfactory and that is echoed by others. It does depend on your customer assignments, though. Even in profitable spaces, however, management seems unwilling to make changes to alleviate this, even when asked directly and repeatedly. There is instead a push to just do more with less, and faster. In my observation, this results in lost opportunities for business growth and career development, and risks high rates of burnout.
