I went through two phone screens and then moved into an on-site interview with the manager I would be working under. I also was asked to provide work samples. Painless and quick. Within two weeks I heard back from the recruiter with an offer. Everyone I spoke to (on the phone and in-person) were amiable and easy to talk to. It was a really positive experience. Even if I hadn't gotten the offer I would have reapplied to Informatica upon graduation.

Initial communication was slow, waited weeks between emails and phone calls. But each time we spoke they seemed excited to talk to me. Don't stress if they don't get back to you promptly, they have more important things to do than hire an intern- same goes for any job.
