If they naively just feed the entire dataset without some inspection maybe. But I doubt the people working on this model stopped at the most basic level. What you describe is a common class imbalance issue. I would expect that they have accounted and addressed (at a minimum oversampling the less represented class for example) for this issue while working on the model. So I doubt it's enough to explain their issue here. I agree that we can't really take any conclusion of their broader hiring patterns from this experiment.
