That is pretty much true with any interview question that does not involve an absolute (i.e. what is the MGTOW of this aircraft?). Most FAA oral exams and airline interviews involve questions that are subjective and whose answers can be interpreted differently. It is near impossible to present any scenario based question that is not subjective and open to interpretation. There will definitely be wrong answers, but there may also be multiple right answers.

I think that Airbum's system, rather his company's system, is probably closer to the best of both worlds. There would be an interview process, but when you take said interview is determined by seniority.

The fear that this would lead to the return of the Good Ole Boy club is a bit unfounded, since the club never left. If the good ole boy club did not exist, then the need to network and have internal recs would not exist.
