IBM

There are a lot of bright people working at IBM.

It's easy to get in contact with people to help you do what you need to do if your manager is any good.

The pay was good for a Junior/Senior-year internship.

I didn't like the corporate culture. Though the development process is relatively well-managed, you're dealing with a slow-moving behemoth.

Managers vary significantly in how much they micromanage. I ran into situations where I was micromanaged in a very negative way, and I've been in situations where I was not given nearly enough guidance, even after asking for it.

Although it is intern work, it feels a bit thankless and meaningless because the projects I worked on seemed marginalized or on the verge of marginalization.

I was dealing with management and coworkers below what I'd expect to see working full-time at IBM. I would suggest making it easier for interns to get into contact with people who can help them become most knowledgeable in what they're working on. IBM has a lot of resources at its disposal, and it'd be great to be able to leverage them when I'm roadblocked. Of course, there's a fine line between leveraging successfully and wasting their time.
