Not in the USA. As a result of a rash of accidents the FAA banned cadet programs, and other bottom-of-the-barrel hiring policies, that put a 150 hour pilot directly into the right seat of a commercial jet. The practice of hiring low hour commercial pilots as co-pilots in a commercial airline has been outlawed. Some cadet programs exist, but a minimum hour requirement is mandated before a cadet hire can qualify as a co-pilot in commercial jet operations....and it’s not 150 hours.
Altough previously first officers were required to have only a commercial pilot certificate, which required 150 hours, the new FAA rule requires first officers to hold an Airline Transport Pilot (ATP) certificate, requiring 1,500 hours total time as a pilot.
More recently, as regional airlines struggled to recruit experienced co-pilots, the FAA eased up a bit by allowing military pilots with a minimum of 500 hours of flying experience to become commercial co-pilots...but a minimum of 1,500 hours is required for non-military pilots.
All this is easily googled...so take a break from your other less pressing office duties and search for yourself.
After all, common sense should tell you that experience is a key metric when determining competence in any profession...especially for one where safety is the highest priority.
Is that substantive enough for you?
