I am a reapplicant so I know how anxious the whole process can be, but a few things to keep in mind:
1. Some schools do run late interviews, it is not ideal but you still have a chance. I just interviewed at TUCOM-CA and they said interviews often run into mid May, and that they usually don't have to ration seats until mid February (in other words this late is still not too late to have early applicant advantage at some schools)
2. I have a friend who got in to WVSOM last year with a 25 on MCAT and similar GPA to you, its not unheard of
3. EC's are huge at some schools. Each school weights different aspects more, and even at some of the top MD programs people with average stats but excellent EC's often get in over people with excellent stats but average EC's.
4. If they offer an interview it means they have thoroughly screened your application and think you are a good enough candidate to admit, while having better stats still help when they decide your fate just getting the offer is a positive sign (for the majority of schools, there are a few that interview for the waitlist or have otherwise unpleasant policies, but they are usually upfront about it and in my experience these tend to be MD programs)
5. Even if you don't get in, if its in your heart don't give up and you will get there. Just focus on what you perceive as weaknesses, save up for applications and apply early.
This is my third year applying, about 10 schools per year, the first two years I received 2 interviews each and waitlist/rejections, this year I received 7 interviews and 3 acceptances so far! Take it from me that if you want it badly enough, it will be just as sweet if you get it this year or next year.
