As Glueball said, it's down to supply and demand and your unique skills.
I've been offered jobs over the telephone without an interview, basically " When can you start we are desperate" and also had to jump through the hoops, sim, interview, trick cyclist.
When it was the "please start tomorrow" they were more than happy to pay because the relative cost of an air ticket and accom was less than having a non op jet.
When it was jumping through hoops it was all paid for by yours truly.
