- Is the job market flooded?
Yes. There are many more qualified pilots than there are jobs.
- How old is too old?
Difficult one this. Some say 30, others say as old as 45 is still ok. But the chances reduce with age, for sure.
- Degree?
Not necessary, although it can help for some recruitment programmes.
- Women?
From personal experience, some pros, some cons, but these balance each other out so there is effectively no difference.
-4 years?
Yes, and more, plus a lucky break or two. There are those who go straight into good jobs, but they are the exception rather than the rule.
I would recommend using the search function, there's a lot of info on age and employment prospects already out there. The gender thing is largely irrelevant, in my experience. Sometimes it works for you, sometimes against, but overall it makes no difference.
