Pros
Great people, good opportunities to learn, great for someone with 3 years or less experience, opportunity for promotions within a year or 2. Get in, get some experience, upgrade your title, then leverage that to get a better job and bounce. That would be my advice.
Cons
Few issues with their business model. First, they are not honest with their clients about their fees. They won't let clients see their actual ad spend for instance, because that would reveal they are charging some clients fees higher than 40%. That was an issue for me. Second, they give their employees 50+ clients to manage at one time. After weekly meetings and completing tasks like launching new clients, you have maybe 10 minutes per week to spend on each client. It's not uncommon for one employee to be managing 75-100 clients at a time and launching 5-10 new clients each month. And that includes employees who have less than a year of experience. Again, I'm sure the clients would be shocked to hear about that, as they are sold on expert management before they sign, but they are kept unaware. If you make a mistake on one of your 50+ clients, your manager will come down hard on you, without much understanding that it's hard to multitask so much. Finally, they would work with clients who compete with each other in the same market. Imagine running ads for 5 businesses in the same town and industry. Big conflict of interest which they look past. It's pretty clear the business model is to churn and burn clients, sign 2 new clients for every 1 that inevitably leaves. Management is either out of touch with industry best practices, such as charging reasonable fees or having employees manage 10-20 clients, or they simply don't care. It's probably the latter.
