Pros
I worked here for a few years and I can say you do meet genuinely nice people.
Cons
Join the tribe.... and that's exactly what it is. The cult at Bulletproof is one of "Eat... or be Eaten". If you do not fit in you will know about it right away. Some people are very politically driven at Bulletproof and if you are working on a project you not only have to work on something that has a ridiculous turn around time because they don't know how to push back on client demands, but you also have to be able to back yourself up when eventually upper management will blame you for anything related to the project you're working on ... even if it's not your fault. The work ethic they have at Bulletproof isn't one of learning or support, they have separated Juniors, Mids, Seniors, Directors onto their own tables, so in other words you have no one to learn from, no one to mentor you. When you are working on a project with other people, it's not seen as a opportunity to come up with ideas together, it's seen as competition to beat your opponent otherwise you will be berated as the weaker designer. The few nice people who you meet along the way, have all been specifically hired as churn and burn designers. They are too afraid to speak up, insecure and basically get bullied into staying really late at night to finish a job. If someone doesn't, they will be fired and paraded around via an email message to scare everyone. You can sense the cult through the positive messages left on this site, each one has been crafted by HR, upper management or one of the "lads" that fit into the regime. You can forget about being promoted or any pay rise. Your "bonus" is an annual trip that is heavily monitored.. think of it like a school excursion. In short, stay clear... you have be warned.
