Before giving out any details about interviews, I would like to convey that the company is often "bad-mouthed." Don't pay attention to Reddit, Quora, or any other sources. While I'm sure there have been bad experiences, those were in the past.

Once you talk to their engineers, you'll get to know the cool and impactful work they do, which matters the most.

The interview process was as follows:

• Online application: Submitted via their careers page.
• HackerRank Test: They sent out a test about catching a fraud. It was easy if you could figure out the long story-like problem. Once you broke down the problem, it was a simple algorithmic question.
• HR Screening Round: After the test, I was reached out to via email for a next round, scheduling a phone call. The HR representative postponed this call multiple times by not showing up at the pre-decided time. This round involved a usual resume breakdown and questions like "Why Palantir?" and "Why CS major?" Note: Do not take this round lightly, as many rejections happen here.
• Coding Phone Interview (45 min): Focused on LeetCode medium and hard problems.
• Coding Video Interview: Included one UI design question and an algorithmic question.
• Onsite: Three back-to-back sessions covering design, whiteboard coding, and decomposition.
• Feedback and Rejection Call: The final step.

[Note: The format for all interviews is introduction, problem-solving, and an "ask the interviewer anything" segment.]

Random Notes:

My application process was quite long. The online test was around September, and the onsite interview was in February. The HR team can be tough to reach during the initial phase of the application, though their response time significantly reduces after you have cleared a few rounds.

Signed the NDA.

I can't give exact questions, but most would fall into the LeetCode hard/medium bucket.
