Probably not popular but, as posted here before, BA interview to fill up the jobs. Once full, interviews stop. That's it.
Therefore the earlier you get the interview the better chance you have of getting in as once 80 (ish) suitable applicants are found, plus a percentage for potential sim failures, this block of recruiting will stop until the next financial agreement.
Thus, the numbers don't matter, the timing of your interview does!
Have fun!!!
