In the event of your successfully clearing the Management Interview, you will be called for a screening on simulator (IPT). The date, time and venue will be advised subsequently. However, you may kindly make arrangements to be in Mumbai for approximately 3 days.
Sounds like if you pass the interview you will be called for the IPT immediately
That could also be the reason why the interviews are spread out very far
I suggest everyone to be prepared to attend the IPT as well
