The phone screen was a breeze and the on-site interview consisted of 45min-1hr interview with 6 different individuals ( 3 engineers, 1 mgr/director, 1 VP and 1 H.R).
In the onsite interview I was not really tested as much as I'd expect. Most of the technical questions were run-of-the mill and only a couple of questions here and there were probing my depth of technical knowledge.
