The equivalent of tech companies wanting 10 years experience with Ruby On Rails (a web application framework introduced in 2005).
"Technicians have to climb 50-foot communications towers, clamber up utility poles and work outdoors through Wyoming winters and Kansas summers. They put in 10-hour days, in clusters of eight or ten days, and are routinely away from home more than half of each month.
....Standing at the front of the room, Ms. Bailey described the deal. As installation technicians, they would earn $21.64 an hour, or close to $48,000 a year for the railroad's regular work schedule.
...After a website job posting, Ms. Bailey initially drew 58 applicants. Of them, she deemed about two dozen sufficiently qualified so that
she invited them to take a $25 aptitude test, at their own expense.
...Ms. Bailey faced more stiff competition at a job fair the next day, because then she was up against several other employers looking for the same sort skilled people as she was. "Make $70,000 - $80,000 the first year with FULL BENEFITS," read a sign at a booth right across from Ms. Bailey's at the job fair, put on by the U.S. Army in Fort Carson, Colo., largely to help departing soldiers ease back to civilian life."
