Im afraid that in the real world 600hrs (Wingbar) does not immediately entitle you to an airline position - particuarly if the majority of that time has been spent in small light aircraft. At the risk of being ranted over, the acquisition of an FI ticket means precious little in the modern commercial world. Yes, I do realise that the likes of CTC are supplying 'cadets' to airlines - why, because they are cheap and a known quantity, even though in my opinion they should be leased out to small turboprop operators for a couple of years to learn their trade before being allowed anywhere near large jet aircraft.
It will come - just lower your expectations a little for the first couple of years.
