@Cecco - usually US based operators look for more hours than us. Sometimes insurances play a vital role in the scenario as well.
I had sort of to little hours no matter how much I had until I had too much !
I started on a little Turboprop, tried to get to a bigger one: no, not enough TP hours. When I had the hours, there was too little EFIS time. Got eventually there, then I had to little Jet experience. Made some Jet time - then I all of a sudden was having too much command time, to get into an airline...
In fact a friend of mine just 'adjusted' his hours down close to the maximum allowable and joined said airline with roughly 3000hrs more than they knew.
If the market ever (I doubt it) turns back, then all the barriers now in force will be gone. That has been the game in Aviation for a long, long time.
