there is already some hiring process in the air , but you should look at the chance to be hired for a wannabe or an hero pilot with 747 experience.Wannabes have no chance to be hired after school.
here my prognostics:
2010-2013: no much hiring, based on who you know or Pay to fly.
2014-2018: airlines actively hiring for 500 h on 320/737, 500h could be waived.
2019-.... : end of hiring process, cockpits are full
2020-2021: crisis due to fuel shortage, poverty, wars,...
2022: like 2010, wanabees asking the same questions again and again....
as you can see, there is no hiring time for a fresh CPL pilot.
if you start your school now, you are wasting time and money!
your only chance is pay to fly( to fly for 6 months), or get a job around 2014.
if you land a job, you will certainly lose it in 2021.
the best time to get a job will be 6 years after the crisis: 2016-2017.
