I remember a friend of mine interviewing there. He was flown from London to SF for the interview. He got through the technical questions fairly easily. At the end, he had an interview with one of the co-founders, who asked him "As an FDE, what do you think your role is?". My friend totally BS'd his way through the response, thinking he's messed up the interview. The founder however ate up everything he said, and added his own flavor of fluff to the conversation. That's when he realised that Palantir was not really selling software, as they originally made out, but consulting, much like Accenture or McKinsey. Needless to say, he was truly disappointed by the experience - Palantir was quite simply not what it was made out to be.
