Pros: Brilliant co-workers, access to clients/projects that typically require decades of experience, a no-nonsense culture that rewards action and mission orientation.

Cons: Flat company structure that can be difficult to navigate without some political savvy. Negligible training/mentoring; mostly trial-by-fire. Small leadership with inconsistent performance.

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.

Pros: Engineers that are talented both technically and in terms of product intuition, in very difficult and important application areas.

Cons: Working long hours is necessary for job advancement. It is difficult to speak about your technical work publicly, which makes it hard to be part of the broader engineering community.
