All successful candidates will be notified through an email from the operations administration if they have passed their academic exams. The email will most likely come out to those candidates earlier than 10 October, maybe as late as 5 October.
The diversity of the candidates might play a role later on in decision making. The flight ops department needs pilots very badly and could be rushed to take applicants who can finish their required training and start ASAP (i.e. candidates with prior flight experience). This can not be confirmed though.
As pertaining to age and other forms of diversity, it will not be a major factor for the hiring decision. Successful candidates are guaged on their performance vide the required examinations and interview.
