I believe that so far everyone who has successfully completed training has been placed with an airline - 100% employment rate.
After completing the CPL/IR with ATPL credits, you then go on to do the Airline Qualification Course and begin type rating for the aircraft you are going to go onto. I think cadets are generally ''tagged'' by the selected airline during the end phases of training.
CTC said that there may be a couple of weeks wait before starting the AQC, I think recently there has been a bit of a holdpool due to the situation with the airlines, easyjet over-crewed and all the mergers.
This info may be wrong tho, maybe someone who's been through the process already can better comment.
