Pays well for an undergraduate intern. 6k per month plus housing. I was in a hotel. Lots of people I knew loved it. Totally depends on your team. Looks good on a resume.

Again, this all depends on your team. My experience was long hours with less than clear goals.

I was given an absurdly difficult assignment. This was later cut down, but only after I wasted three weeks trying to solve it (a significant portion of a 12-week internship).

The assignment was not possible with the codebase I was working with. I got off the project only after I showed my manager that it would require a total refactoring—think five people working for six months—to get it working.

The assignment I was given to replace the previous one was vague. It was boring. I did it, but I hated it.

Huge difference in quality of internships. Some sort of way to keep these balanced would be great.
