In my experience, they concentrated on the following:
IR test(s) - recency and number of attempts
Multi time logged
Recent flying - how much has this candidate done in the last year/6 months/month, what type of flying has he done and what aircraft types has he flown. One interviewer scrutinised my logbook and said "I see you've flown a Piper Arrow, tell me how the retractable gear mechanism operates".
I doubt if any airline recruiter has the time (or the will) to scrutinise and analyse all the entries.
I'm now happily employed in an airline job having failed the nav section of my PPL.
