I think it's only after the last 9 or 10 years that the new way of interviewing potential medics (MMI) has come in.
Whilst it's still not an exact science, it invesigates and probes the potential students' softer skills of communication, ethics, interpersonal skills, and collaboration.
Much more than just entry-qualifications of 'yay, you're likely to have great A levels, come on in and be a doctor'.
I suspect there's still a huge hangover in training timelines for those who are fit into the 'yay, you got good grades' in the medical profession, so my expectation of their skills in humnanity remains low!
Harrop, Jessen et al are just products of the system that didn't care about your softer-skills, just went with 'are you a bit clever and can you study well for your A-levels'.
