Pros
You'll learn a ton and have so much scope - scope that you're probably going to be scared to take on, and no one will fight you for it. When I first joined, this was my dream! Read: Big Tech PMs and MBA grads, this could be an interesting opportunity for you. Some other benefits include Caltrain commuter benefits (Box is located in downtown Redwood City right above the train), and like most tech companies we have snacks and an in-building cafeteria and coffee bar.
Cons
Product strategy is clear, but questionable. The way that products are shipped at Box always involves at least 3-4 scrum teams to ship 1 thing so naturally, shipping takes a long, long time, if it happens at all. Urgent customer requests come in constantly at a rate that the teams are unable to ship. PMs have a lot of scope, but very limited impact, so unsurprisingly, the PM org goes through a lot of burn out and churn. PMs are then expected to fill in the gaps, which are massive due to limited to no resourcing across design, user research, and analytics. There's an overall sense of nepotism at the leadership level and leadership continuously hires more Director-level PMs to do IC work, because there aren't enough PMs to do all the work. And to boot, no 401k matching, compensation is lukewarm, no bonuses for PMs under Director level, and no stock refresh until your 2nd year.
