Hi
ankiprat001,
the fact that some applicants have received interview invites and you haven't doesn't mean anything. This is the same story every single round.
INSEAD is a very particular school in many ways and one of them is that interview invites and final decisions are released little by little over a period of time (usually 2 or even 3 weeks). This creates anxiety among applicants and they wish INSEAD would take the approach other schools do, i.e. just release all decisions at once.
Also, the time you get your invitation has nothing to do with how much they have liked your application. Or if you submitted your app early does not mean you'll get your invitation early.
Anyway, INSEAD will be sending interview invites every day until October 12th, so there is still plenty of time for you to receive yours. Just wait patiently.
Warm regards
Alex
