considerable experience on the boeing 737

[born to suffer]

Hi guys

At qatar airways web u find this sentence

"Pilots with considerable experience on the Boeing aircraft (B747-400, B767, B757 & B737NG) will be considered for a type-rating conversion on the B777"

so how many hours do you need on b 737 NG to be concider as a pilot with conciderable experience

As far as i know, an (ex) colleague of mine joined QR on B777 as FO with around 4000 hours total (2000 734 and 2000 737NG).
