I am a strong believer that 600 hour pilots don't belong in an airline cockpit carrying passengers around. I dont know waht the magic number that qualifies you for that would be however, so who am i to say you shouldn't be ready at that low time. My gut does tell me though that around 1200 TT and over 150 multi you should be ready for anything.

Sounds to me like you just threw the towel in and gave up. That attitude won't get you a job in most places.
