I applied through a recruiter.

Went through ~4 rounds total. First was standard recruiter convo, then the Karat screen which was a mix of resume walkthrough + a few coding problems in one sitting (timing is the tricky part here). After that was the onsite loop. Onsite had decomp, learning, coding, and a behavioral.

Decomp was more like breaking a problem/system into smaller parts and thinking through design choices, learning round was about picking up something new mid-interview and applying it, and coding was standard DSA but they want you to be very clear with your approach. Felt quite different from typical big tech loops - less about memorized patterns and more about reasoning through unfamiliar problems and explaining your thinking clearly.

For prep, I focused on LC (mainly mediums, with extra emphasis on graphs and trees), some low-level design, and practicing how to communicate my approach. Grokking helped for system design. I also did a mock interview on Prepfully with a Palantir coach who helped me with the decomp round a lot. Also skimmed Blind/Reddit as well to get a sense of how the rounds play out.

Design an in-memory database that supports basic CRUD operations, transaction rollback, and querying by multiple fields.
