Their requirements are high however they are really looking for people they can give quick command upgrades to,not people who are going to sit in the right seat for years.
They also mention nothing about age restrictions,however based on past recruiting they will take people up to the age of about 60,obviously with experience however not necessary with time on types or time in country. Getting people to be POM based will also be another major issue,especially how PX (mis)manage the accommodation for their staff.
