Pros
There are bagels on Fridays, some company outings, massages, dinner/drinks, and other activities outside of work.
Cons
Glassdoor is quite accurate; particularly the statements on listening to and valuing employees. While the perks mentioned above are nice, where the rubber meets the road is how people are valued, and the subtext is quite clear: they are contractors in a cost-center, and management really cares about reducing cost above all else. This manifests in a few ways that hurt innovation and employee initiative, namely an over-focus on Jira ticket management, and only top-down waterfall-designed projects get the green light. There's a real chance that you won't have any real input on the projects until it's time to implement them ticket by ticket... unless you get shuttled to a project elsewhere in the firm (or wider family of non-finance Peak6-owned firms) that needs a better ticket-closing rate. If you're after a place to be creative, innovate, and work on interesting things, consider working elsewhere.
