I had only one interview with both technical managers and hr. It was one of the worst and "cold" interviews I had ever had. Fully formulaic, questions only about what I did before, never discussed about technical stuff. At the end of discussion there was a confusion for my match to the role, but after a few minutes they were convinced that I can be part of the team technically. I got the offer later by the hr and I asked if everything discussed was immutable. They said yes. And later when I entered I went to a different team and I had no clue what they were doing...
