Had 4 rounds of interviews in total. Was told after the third round it was the final round and I felt pretty good about it but 2 weeks later there was another round.

One thirty minute phone call, then superday consisting of multiple interviews. Phone call was very straightforward, mostly behavior and then asked the lily pad and oil change questions that are listed below. Superday was three interviews, with gaps between each (of varying time depending on scheduling), pretty much entirely behavioral. Very, very laid back process.
