It's just like job interviews: any given program will basically have their top invited candidates, their alternates, and their "no way" pile.
Most of the programs that get a lot of applicants offer interview to 3-5x the number match spots they have, they see what happens, and then they may invite a few alternates if more than a few of their top people decline.
...As was said, check with the program coord after a week or two to see if your request has a response.
Asking your classmates is dicey imo... some people are fairly helpful, but the majority are kinda very cloak-and-dagger about anything to do with match (esp if they're trying to interview/match near the pod school city). Some people throw smokescreens and BS you intentionally about what they are trying for, what interviews, how they rank, whatever. It might be for ego, personal gain, or insecurity. The match ratio of students:spots are getting very tight again... so that does not help any potential cooperation and support. For the good students, match is usually a good time, but there are still only so many spots at good programs - esp good ones in the popular areas. The average students could have an easy or impossible time in match - depending on where they try for. For the bad students, match is likely to be the affirmation that they should've worked harder in pod school. Very few will be on top of the world. People get very edgy and have emotion extremes; everyone is out for themselves.
It sucks, but you're honestly best to, between now and match, mostly keep to yourself or socialize mainly with non-pod friends or classmate friends who are going for few or none of the same programs that you are. You really want to be polite but curt and keep stuff under your hat if random people in your class are suddenly friendly and ask you where you are interviewing, where you externed, ask for info on other classmates, etc. Match day itself (and therefore start of scramble) is a good day to skip class; no joke. It is fine to go to school that day (especially if you know your match based on clerk/interview)... but you want to stay farily reclusive as you will definitely observe some pretty roller coaster emotions.
