Virtual interview is definitely not the same as in-person interview. During the in-person interview day, you are watched from the moment you set your foot on the door until you leave. Every interaction - with PC, residents, and fellow applicants is used to get a good feel for applicants. This sounds silly, but these "meaningless" interactions do play a big role in judging an applicant on the interview day. After all, interviews are all about "the feel" and seeing how the person will fit with the residency program. This also meant that applicants could potentially influence the rank position based on their interview day performance if they really knocked it out of the park with the fit.
Virtual interviews are great for exchanging information, but is limited in the ability to assess the subjective feel that you can get from in-person interviews. Not saying it is impossible, but this will make it more difficult for applicants to really sell themselves to the programs. At the same time, programs won't be able to thoroughly evaluate candidates as well either. Given this, if I have to make a guess, I would agree with above posts that programs will likely to have bias towards their own students. I will go one step further in saying that students with better objective measures will also be favored too, more so than in the past. It all comes down to programs not wanting to risk having subpar residents or residents at risk of failing board exams, and the safest way for them to recruit is to go with their own students whom they know well or with high scoring applicants who likely will not have any issues passing boards.
One thing that is likely working in your favor is that programs are likely interviewing more applicants than in the past because applicants are simply applying to more programs - more overlapping applicants across the country and puts programs at risk of going further down the match than usual. You may be included in the broader net. It is still early, but I would be active about reaching out to programs if you don't hear from them by thanksgiving. Lastly, 220 on step 1 is about 40th percentile, but 220 on step 2 is close to bottom 10-20 percentile since passing for step 2 is close to 210. That is a significant drop, so I would explain it to the programs during interview. Hopefully programs will be understanding and will look past it, although being bottom quartile isn't helping you make your case either...
Having said all that, assuming you are an USMD, I think you will be fine with matching. If you are really concerned, I would apply to several community programs if you haven't included them on your list already. Good luck.
