Lengthy. Applied in September. First Interviewed in January. Total 3 rounds with the manager, two Senior Manager. Screened by Recruiter initially. Interviewed for US delivery Center. Mostly about technical and behavioral. Each half an hour interview.

Initial call was from experienced hiring team seeking to know more about my experience and expectations. Duration was about 15 minutes which ended with them saying the next round would be with a Senior Manager from the team that has the requirement. After a couple of email exchanges to schedule a mutually convenient time, a telephonic interview was conducted. This was the "technical" round and went well with the interviewer genuinely wanting to know more about my work. Duration was roughly 1 hour.
