As you say, there are hundreds of posts on CTC already. I'd be concerned that you wouldn't be able to get everything passed before your 34th birthday. How long is that? It's probably worth speaking to CTC to find out when they intend on re-opening the ATP route (currently closed because the hold pool has loads of people in it).
Also consider that there are integrated schools out there which have a very high number of students that go straight into the airlines. You should consider what you do if you fail the CTC selection process.
How many get jobs? as far as I know everyone that has got through the selection process, type rating and line training have been given full time contract. Many people don't make it through the selection process and I've heard that a couple have been kicked out during type rating or line training as they could not reach the required standard.
