Pros
one upside of them trying to move fast is you will get to work on latest technologies but all of this comes at huge cost to you personally. It's a good place for fresh college grads but everyone else not the place to be.
Cons
Frequent reorgs and top level management changes all through the year. I have had 4 reorgs in less than 3 years of being there. Whenever someone at the top leaves, management takes it as an opportunity to reorg the deck across the division. One of the most regressive performance management process I have seen which they take great pride in, it's done 4 times a year with no time for associates to focus on learning and development - it's deliver or out all the time but when you couple that with the frequent reorgs it's hard to settle in a role and deliver. Very short term focused managers. Managers are not interested in your development, they just need results to go after their promotion. They run quarterly survey on employees but managers are busy trying to figure out who gave bad ratings than focusing on how to improve morale. There is a lot of corporate marketing speak which is says and means two different things. Be prepared to just preparing atleast 100 slides a week, that's all there is to their work.
