Thanks, I think I understand. You had completed three steps, thought there were two left, but out of the blue you were told that there were actually four more, because that's the new process they're moving to. I've never interviewed for a FAANG, but I understand that they can and need to be very picky, and can typically get away with things like seven round hiring processes. I still think it's disrespectful of your time not to let you know the whole process up front, and then sticking to it. Best of luck to you!
