Pros
I worked at Coalition Technologies for about 1 year as a Digital Strategist. Coalition is probably the coolest digital marketing agency out there. The hiring process was intense. I took some tests, had a couple of interviews (as I remember), and submitted a short, Facebook-like video during the hiring process. I got the offer about 6-8 weeks after I originally applied. Pros: First off, Coalition provided me the opportunity to work from the comfort of my home office. Although I did venture out on a few occasions for partner or team meetings in town, the overwhelming majority of days were spent at my desk chatting with clients and prospective clients. Second, I learned a ton about how a digital marketing agency ought to run. You don't know what you don't know and didn't know how useful GSuite could be, how helpful established processes are, or how crucial good training is to a growing organization. Third, my experience with Coalition was overwhelmingly positive. The collective professionalism and abilities of my colleagues was easily the best I've experienced in my career.
Cons
From a employee perspective, it's hard to point out any improvements to be addressed. The management team was very open about wanting to improve processes and frequently queried employees about suggestions. In fact, if I didn't give feedback for individuals in the previous 7 days, a friendly reminder was sent saying it's time for more feedback. In other words, if I wanted to improve anything I just submitted the request through management (even directly to the CEO) and there was no fear of negative consequences. And they did listen to my feedback and made adjustments.
