Pros
For the most part, you get to work with smart, generally amiable people - this was an enjoyable part of the company and something you will hear often, the Culture. Leaning in to a transparent framework when it comes to re-orgs & big changes so the employees feel their input is heard.
Cons
If you are at a lower-level status, your enthusiasm to succeed and find a place within the company is quickly met with false promises and deflection. There is no line drawn for the demanding workload or expectations as a contractor (such as training formal employees), but once you seek answers or feedback upper management will quickly remind you of your place. There is less of a focus on the work being produced as a top performer, rather your final outcome of advancement is more of a crapshoot of timing and what department you are in. There is proven record of even the most deserving of contracted employees being terminated while the "lucky ones" get to move forward in the employment process. It is well versed by the veteran employees that this is a sad, unreasonable trend that has risen over recent years. Another problem at Crown Castle is that how well you do is more of a matter of perception than the actual work you produce. Even if you're often identified as a good performer -- if you aren't vocal and toot your own horn to management, you are unlikely to advance quickly. You have to be your own advocate, which can be true in most work environments, but for the people who are more interested in focusing on the actual work and demonstrating their value that way, there isn't time partiality. Standards aren't uniformly enforced either. In fact, you will likely spend much of your time learning the daily work and systems on your own. Whether your team is helpful and/or encouraging is a big component of how well you do rather than the company providing the necessary tools and resources to succeed. Unfortunately it sounds like this will be a common factor during your entire time at Crown Castle, as there are so many changes and reorgs that regularly occur.
