They arranged for multiple rounds. First an HR just asked general questions mostly pertaining to background and previous experience. Then there was a voice clarity round with was telephonic and automated. The IVR would ask you to repeat phrases and answer questions to get an understanding of the overall quality of your voice. Modulation is also checked probably. The next round was an ops round where they asked technical questions. The questions would not be easy unless someone has previous knowledge like I did.

Pretty quick, applied for the position and 2 days later got an email to schedule the in person interview. The actual interview itself consisted of many situational questions and "about me" questions. Very comfortable environment and the interviewer made it that way.
