Submit resume/experience/application online. Then contacted about an entry exam totaling 5-8 hours. Given extensive study materials and instruction videos. They make it clear that if you have an issue, you should review every part of every manual to ensure it's something you can sort out yourself. If you have any problems with the entry exam, they have no way of helping you (you have to go through the vendor). The entry exam questions are HIGHLY SUBJECTIVE and open to interpretation, but they still expect just one right answer. Overall many hours wasted on a job that does not pay highly.
