I have applied for this job through Parc twice now both times didn’t get past sending in the application.
I have a total of 8200 hrs with + 5000 hrs command on medium Jet B737-200 and 800.
Also have a small amount of 4-engine DC-8 freight time.
None of the above helped so I can only imagine that you need to have 747-200 on licence.
Good luck with your application.
