Both comprehensive and thorough, the team was good to work with throughout. Long process from start to finish but good HR department. More of a get to know you in the first phase, second phase a bit more finite in questions. Technical questions came up throughout but were not the ultimate emphasis, if you interview well you will likely get bumped to the next round where the interview is with three to four members of different groups who ask very different questions. Then after that process, you will have two final interviews with the group heads and they ultimately have to give you the okay.
