I would like to add that they have no streamlined process. There are no set questions everyone is being asked. They conversate with you like you are their friend, like you're a shoe-in. Then they apparently ask each individual different things. I know this because when I was down to one of three, I was rejected via email, not even given the decency of a phone call, and at that time I was given information as to why the winning candidate was chosen over me. and it was a topic that had never even come up in my interviews. It was beyond unprofessional, and this from the person who does this for a living.
