Pros: Interning at Microsoft was a fantastic experience. They have enough events to keep you wildly busy, and the Intern Signature Event this year was Daya and the Chainsmokers. Overall, a very wonderful experience full of learning with lots of great peers and coworkers.

Cons: It's not to say that all interns experience this, but my manager was absent a lot, so I had to struggle on my own.

Pros: I get to work with intelligent and supportive teammates every day. Amazing facilities and a gorgeous landscaped HQ. Work/life balance is very good for most SWE Interns I know. Free drinks. They bring in good musicians to play over lunch at the main cafeteria. Performance feedback is not only focused on individual contribution but also on how well you work with others. I've been told this really improves the company culture, especially on the main campus. They make an honest effort to give interns projects that are interesting and within the scope of a summer. Top-notch health insurance, even for interns.

Cons: The culture of different teams can vary. (I have heard good and bad from other interns.) Microsoft always manages to stay in the news with the latest PR gaffe. (Honestly, more amusing than upsetting to most employees.)

Pros: Probably the best intern salary compared to Google, Apple, and Amazon, especially given that in Washington prices and taxes are lower. Subsidized housing.

Cons: Tools are definitely not very good, build system, source control, etc., etc., etc. But this is going to get better soon, I think.
