F2F call at Mumbai office with a day (24 hours) notice so they see if you can make it to take it up forward. Interviewer would have one time slot during a week. if you say that I can't make it tomorrow they might cancel your candidature or give you time slot after 2 weeks. Their process too short for hiring but time of interview longer than you may expect ever 3 hours long and discussing with almost 5 people in many rounds will make it real challenging situation for interview.
