Initial telephone call with HR person. This person "followed" me through the entire hiring process and it felt very salesman-like. Looking back on this I can see why. Within the Bay Area of where McKesson's headquarters is located the local reputation is an employer that does not treat its employees well [bad work life balance, etc.]. The onboarding was latterly that, I signed my offer letter and that was it. There was no official new hiring training, etc.
