My understanding is that Palantir is running an engineering mill/sweatshop using fresh out of school CS grads (particularly from Stanford). That much of their time is spent simply writing client-specific code that imports and cleans up data from disparate enterprise systems. That its not challenging, innovating, or exciting. Of course this is all anecdotal based on what I've heard from friends and a Palantir engineer…
You hear quite a bit about Bay Area companies paying top dollar for fresh CS graduates from top ranked schools. I wonder what compels a Stanford CS grad to take a job doing non-exciting work with a company that prides itself on paying below market rate. Maybe it's the code names?
Their pitches of "We only hire the best and brightest" and "Our work truly changes the world" sold me on them.
