Sure, but that doesn't mean they're a good doctor. Most of us have had experiences with bad doctors. The exams they took could have been decades ago, but what does that tell us about how they've performed recently?
Bad doctor is relative. I expect that most doctors who have pass through that gauntlet can pass the doctor equivalent of fizzbuzz, which already is a lot different than our industry.
A doctor equivalent of fizzbuzz could be “what do you prescribe for a viral infection with no indication of a secondary infection” and from what I’ve heard there are a lot of doctors failing that one during the COVID pandemic by prescribing antibiotics.
They are highly effective at making patients stop begging for antibiotics they don't need. Patient satisfaction with their doctor has nothing to do with medical outcomes.
It's quite hard to be really bad physician - because Pareto principle applies to medicine. As far as I remember, 5 autoimmune diseases (of >120 described; ~4%) make up for 80% of total autoimmune diseases. My relative did research on kidney diseases and results were similar.
