Typical Interview process with recruiter screen, followed by few phone interviews and an on-site interview. The screening process met my expectations but the on-site demonstration required preparing for the demonstration requiring some amount of preparedness.

Several phone interviews. Then they have you come to HQ to give a presentation. If you are from out of town, they will pay for the flight, and claim they will pay for the hotel, but you will arrive with nothing paid for, and have to fight to get reimbursed. (I still haven't been) Before you go, they will say you don't need to know their application, because they will train you once you're hired. They will also say you don't need to know much about API development or middleware, because nobody in the interview expects that, unless you've worked in that space. Then, when you get there for the presentation, they will grill you mercilessly on everything they said wouldn't be asked, and insist that you give them a demo of their product. This wasn't a job interview. It was an ambush.
