If your type rated and current on the CL/NG then an interview will likely follow, for basing the companies objective is to get people to where they want to be within 6-12 months within the confines of the base structure and core restrictions.
If i recall a further 8 738 due in 2014 and 4 or 5 still to come this year so an extra 12 or 13 aircraft, less any CL disposals
I have done over 12 months and they do what they say on the tin, money is very good, excellent training and a very positive passenger experience suggest they'll be around to stay.
You won't probably know your base until after 2nd week of starting and some do end up in core bases on short term contract (with additional cost of living money) to ensure correct mix of experience with so many new crew.
