Got invited to Chicago after I completed a on-campus interview successfully. Stuck us in a room for 2 hours, no breaks, three interviewers. Didn't see the office at all, didn't offer us any food, was a terrible experience. Two interviews were behavioral while the third was supposed to be a presentation about something you've done. It was uncomfortably easy, I didn't want to work somewhere they didn't even ask a decent programming question. Reimbursed travel expenses promptly and recruiter was pleasant to deal with. Office building was gorgeous but I'm so mad they took us down some shady hallway and stuck us in a room. If they would've just showed me the office, I would have at least considered them.
