Pros
Palantir is a unique place to work right now. The business is growing in all verticals including the government and commercial businesses. Because of the explosive growth employees are asked to step up and own large and complex projects almost immediately after hired. The ability to be part of an explosive growth company is exciting and gets me up in the morning ready to figure out whatever new thing comes across my desk each day. In addition to the ability to take on incredible responsibility quickly you are surrounded by some of the most talented engineers in Silicon Valley. Software is treated more like art at Palantir than science and that framing allows for extreme creativity.
Cons
Like every coin there are two sides. The explosive growth leads to organizational complexity that can sometimes lead to newer employees feeling confused or lost in the hustle. Likewise, the creativity that Palantir approaches software development with sometimes leads to pushing out products which are not ready for prime time. Both cons are somewhat mitigated by Palantir's leadership extreme focus on managing the growth of the company. Leads are very transparent on all operations and have a 'door is always open' policy for hard discussions with their team.
