Hey,

To be Very honest the MBA colleges are pretty strict when comes to their PI scheduled date. You should have been a pretty active about your dates by constantly checking your mail if you have applied for the college.

Now what's done is done, still I will suggest you to talk to them once regarding this by giving a legit explanation. If the interviews might be going and they find your reason legit they will reschedule your interview.

But it's just a possibility and you can't do anything else also. So I will suggest you to reach out to them about your concern.

Hope that helps.

Thank you.
