An HR briefing, a first level of technical interview with an L64 dev, followed by a full day of interviews with a L64 test, L64 dev, L64 test, L65 test. Then I was called for a 3rd day to be interviewed by a Director (Test) and a Director (Dev). I think they were undecided whether to slot me as a L64 or L65. Finally I was offered a L64 position.
