Pros: Really smart people to learn from.

Cons: You might feel inferior at times.

Pros: - Still some smart people left. - Decent comp (if you joined pre-IPO). - Used to have good perks, but most of them got cut during the pandemic and with constant cost-cutting that started in advance of the IPO.

Cons: Poor work-life balance. If you don't mind 24/7 on-calls and frequent "surges," this is your home. Professional growth perspectives are virtually non-existent. It's all very random and mostly luck/politics dependent. If you are "unlucky" and got assigned a crappy team/project early on, you will struggle to ever get considered for anything better. You will not learn much and just get stuck. There are few good teams, but since most others are so mediocre, you are unlikely to get into a good one, and moving "upwards" internally is very hard. It's worse if you also get a lead (Palantir term for "manager") who lacks motivation, time, or power to support you. As burnout gets more widespread, more long-timers either quit or become jaded and stop caring; the chance of getting such a manager is higher. In terms of coding, you will mostly fiddle with internal frameworks. If you are "lucky," you might get to work on something new; otherwise, expect vast legacy codebases with plenty of tech debt and support issues. Or they could put you as a "dev" on infra. Leadership is still rather inexperienced and often not sure what they are doing. They try to call it "flat structure"; in practice, there are few unofficial "power clusters," centered around people who are actually important, and their decisions are enforced. Some got this authority by merit, others just by being close to founders/directors, "tenure," or being good at office politics. The result is low transparency on decisions affecting you, wasted effort, and frequent reinventing the wheel. If you are extremely unlucky, they might put you on BD (business development). The main purpose of engineers there is to help customers use Palantir products, especially when they break (and boy, do they break often). Once you are in BD, Palantir will not let you "escape BD" until you quit.

Pros: Mission, the impact this company has and the impact you can create as an intern is amazing. You immediately work on hard and important problems, with no side projects to keep interns busy. You're treated as a full-time employee for the most part. Culture, the people are among the friendliest and smartest out there. You can ask anyone for help. Further, from the constant internal dialogues, you can tell the company is ethically-minded and pursues success with integrity. Support system, mentor/lead/team/recruiter are all actively helping you make the internship a great experience. If there's a problem, you can raise it and it will be addressed. Personal growth, you're given a voice in what you want to do and what skills you want to improve. Travel, we had the opportunity to travel across and out of the country as interns. Perks, the free housing, 3 meals a day, the haircuts, the massages, etc., make life quite comfortable. Intern cohorting, interns in an office got to know each other pretty well and we've become friends throughout the internship. This is just my experience, but my experience isn't uncommon from what I can tell. Compensation, one of the highest out there.

Cons: Finding your own work-life balance. Because of the flexible hours, it can be difficult to find a balance that works for you when you see coworkers arriving or leaving at vastly different hours. That said, I didn't feel any pressure to work late or get in early. It's just a matter of doing what's best for you and communicating that.
