I was contacted via email to set up phone interview with HR which was then followed by on site interview with a director and 2 managers individually. Since I wasn't extended and offer for this position I was then referred for another which I interviewed with 2 directors individually on site. I was extended an offer by the end of the week, the total process took about 2 months.

Fairly straightforward, 1 call with HR, no interviews with the hiring manager or team leader / members. HR offered minimum in salary range I was asking for within a week from interview date.
