Funny you say that. Finding a job recently, Palantir was the absolute worst at the recruiting process. At the end of their two months, in one two-week span I interviewed at and received offers from two much smaller startups. I told my recruiter at the end of the all-day interview that I needed to make a decision by the end of the week on other offers (it was Monday). I didn't hear from her for another ten days, at my prompting. She was frazzled, passed me on to another recruiter, who asked if I could come in again for another all-day. Needless to say, I declined and went with one of the offers I already had.

That's really too bad. I don't work with/for them, but I know many of the recruiting team and they have been very responsive to feedback in the past. If you have specific comments/critiques feel free to message me, I'd be happy to pass them on.
