Deployment Strategist Interview Experience
I went into the decomposition round expecting a consulting case, and that was the exact wrong frame. What they really cared about was whether I could take a huge messy problem, turn it into data and logic, and bring them along for the ride.
Interview process
The biggest thing I remember is that there really was not one clean, universal loop. The front of the process was mostly motivation and fit, then the core of it was technical plus decomposition, which was easily the most distinctive and intimidating part. I went in expecting the decomp to feel like a consulting case, and that was exactly the wrong mindset because they really want to see whether you can turn an ugly ambiguous problem into smaller data-driven steps. Later rounds felt more tailored to whatever concerns were still open, and even the 20-minute conversation after the "main part" still counted. The whole process felt like they were testing whether I could learn fast, stay calm under pressure, and operate with very little structure.

Interview tips
I would tell a friend to stop treating this like standard SWE prep plus a case interview. Do the obvious stuff and get your DSA/SQL to the point where easy and medium problems feel automatic, but spend most of your time getting good at decomp. I would practice a repeatable structure: clarify the goal, write the problem statement, name the metrics and gotchas, do root cause analysis, generate a few solutions, then talk through the data model, the query you would write, and the pilot you would run. I would also actually go use Foundry beforehand, because if you walk in acting like Palantir is some black box, that is going to read as lazy fast.
Company culture
I saw a company that hires for raw capability, communication, and appetite to learn fast more than for one narrow background. The process changes a lot depending on whether you are being recruited to a specific team, whether it is USG, and what concerns come up in the loop, so there is less of a rigid playbook than people expect. The environment they are screening for is long hours, a lot of grinding, and a very freewheeling setup where nobody is going to hand you perfect structure. Interviewer style also varies a lot. Some people apparently stay silent and watch how you react, while others push back on purpose to see whether you can adapt in real time. They also care way more than people think about whether you can think in terms of data and explain your reasoning clearly to non-experts.
Questions asked
Overview
The hiring manager round sounded less scripted and more like a targeted stress test on whatever concerns were left. I also would not treat the casual conversation at the end of earlier rounds as off the clock, because that part was still evaluative too.
Question types asked
Specific questions asked
Let me dig into that concern a little more.
How would you handle that on a real team or with a customer?
This round zeroed in on whatever looked weakest from the earlier interviews. The goal is showing you can take pressure, communicate clearly, and still sound thoughtful when someone pushes into the areas where you are less obviously strong in.
