First round was Karat Interview, which is a third party interview platform. it is is 45 minutes (can't remember exactly) round in the order of self-introduction, time complexity analysis questions and live coding questions. I recommend focusing on the completeness of the solution rather than the efficiency. I passed the Karat interview and had a pre-screening interview with Palantir recruiter. Then got rejected and told me there is no suitable job position for me.

I had behavioral interviews and then 4 in person interviews. The behavioral was straightforward. There was also a data query interview where they taught you a new "language" and had you execute basic queries in it. Then there was a system design interview. I had two of these. The last one they asked me if I was deployed to the moon to identify new species of alien what kind of system would I build.
