After I applied, I was sent a 3 question HackerRank technical assessment covering SQL, API calls, and an algorithms question. After that, I was contacted for an HR call, was asked fairly standard logistical and behavioral questions and moved on to a technical interview over video call. The question was related to playing a unique card game which lasted about 30-40 minutes with no behavioral questions. For 15 weeks, I received nothing about the job and assumed I was ghosted. Out of the blue, another recruiter reached out asking if I was still interested and explained I was continuing on to the next round. This round consisted of a technical decomp question and a learning interview. I had no prior experience in system design for the decomp question, but managed to do alright. However, the learning interview was with another Palantir engineer and his instructions were very unclear, leading to a lot of confusion and I didn't progress very far. Afterwards, I received an email stating I would not move forward - I'm assuming it was from my poor performance on the learning interview but I received no explicit explanation.
