It wasnt much difficult. Though they are very slow in dealing with interviews, almost took a month to get to the final round for technical interview. afterwards manager round and then offer release.

Three interviews, First with Recruiter, then with a technical peer then with the project manager of the project you will join. Interviews vary based on the responsibilities of the role. When you pass the first it will lead you to the second, and same passing the second will lead you to the third. you might have more than one technical interview/ PM interview based on how many teams/projects you applied for.
