Very detailed and very professional. First round would be a telephonic mostly random technical question and resume screening. If that goes well, candidate would be called into office for a series of interview with team mates, leads, architect & senior managers. There could be a written test followed by technical rounds. If all goes well, couple of days later you might get the HR interview.

it was great and quite competitive and consisted of multiple stages including an initial recruiter phone screening, a rigorous technical coding assessment testing data structures, followed by several consecutive deep-dive behavioral interviews with senior leadership.
