It would take a full day, face-to-face interview. Prior to that, you have to qualify by telephone. This telephonic stage would be to qualify yourself and determine whether you are worth calling for a face-to-face.

Most interviews happen on the same day. If an initial interview isn't very positive, they still conduct the other interviews and make a decision after the HM (Hiring Manager) round. This approach is neither entirely good nor bad.
