Phew! Been lively on here this morning. There's a few things I'd like to reply to but don't have time at the moment. I'll reply to the one that was specifically directed at me...
Re effectiveness of face-to-face vs online interviews, I don't think there's really a consensus. However, this is partly to do with different formats of and approaches to interviews. Without giving away any privileged information, I'd say currently about half of medical schools feel face-to-face works so much better that they will make the necessary efforts (and take on the necessary costs) to run them for 2023 entry if they can. The other half feel either that online interviews work just fine or else that the advantage of face-to-face isn't large enough to justify the costs (in staff time, use of space, etc., as well as accounting costs). Also, we do generally feel that having to travel to interviews is a problem for less well-off students, both in terms of expense (only a minority of medical schools reimbursed travel expenses) and of lost school time.
While I'm reluctant to plead poverty on behalf of universities, there is also the issue that income per student is fixed and the value of it decreases every year, especially with inflation rates as they are now. Many universities have had to expand student intakes across all their uncapped courses over the past couple of years to try to stay afloat financially, and this makes finding space to do face-to-face interviews almost impossible for some universities.
I don't know any interviewers who wouldn't prefer face-to-face. (Well, they say that but then they complain bitterly about parking when we ask them to come and interview in person.) In fact, I have a few interviewers who refuse to interview until we revert to face-to-face. Depending on the style of MMI station or equivalent task in other interview formats, I'd say some actually work equally well face-to-face or online, while others work slightly or much less well online. I can't think of any I've seen or done that work better online, although I think my counterparts in some other medical schools would say they do have examples. However, I'm not convinced the face-to-face interviews are so much better that they justify taking students out of school/college for a day (or possibly two, depending on geography) and asking them to pay tens or hundreds of pounds for travel and overnight accommodation.
Because online interviews were forced on us in 2020-21 and many of us hoped to return to face-to-face in 2021-22, I don't think the online interviews were designed as carefully - with regards to being suitable for online use - as we would have wanted. Those medical schools that are continuing with online in 2022-23 will have reviewed the content based on their experience and understanding of how things work online to overcome some of the shortcomings that might have become apparent in what they've done for the past 2 years.
Something I noticed pre-pandemic, and this was confirmed by discussions with teachers in high-achieving schools, was that medicine offer-holders were much, much more likely to drop grades in their A-Levels (especially chemistry) than students with offers for other courses. I'm sure - although I don't have experimental evidence - that this was because of all the distractions, including aptitude tests and interviews. Now, students will still probably be spending more time on interview preparation than they should (that's a separate conversation), but at least they are not potentially losing 4-8 days of schooling to attend interviews if they're online.
