Met at career fair for their summer internship, got a phone interview, moved on to next round which was on-site in Reading, PA. I had to give a technical presentation about a project I've done in the past. Then, went on a site tour of the office. After my interview, I didn't hear back for a while. I reached out to them asking about any updates on my application and she said they were impressed with my interview but haven't made a decision yet. Never heard back from them again which I consider extremely rude since I drove out there for an entire day for the company. They should make it clear that they want Co-Ops, not summer interns so they don't waste anyone's time.

Awesome! The second round is around 90 minutes long where they ask about yourself and what you do, then you present to them a topic of your choosing, and then end by asking questions.
