Pros
Pop Art really invests in people, both in their capacity as individuals and as part of a team. The office is a collaborative, creative environment where people are encouraged to learn from one another and support one another. Employees are smart, personable, and eager to work together. There is a great deal of room for personal and professional growth; I've always felt supported by management to pursue my career goals. Lots of great benefits (healthcare, snacks, ping pong, company events), good sense of work/life balance, and a really cool new office space.
Cons
The fast-paced nature of the company can make it tough to wrap your head around ever-changing requirements. Expectations aren't always clear beyond the vague "do great work," so a sense of discipline is a must here.
