New CDL driver

Here's what I have going on. My brother-in-law is wanting to drive trucks. He's been driving passenger vehicles for a good 30+ years. He let his license expire. I don't know why he let it expire but he moved states and now the state he has moved to made him pass all the tests again which he passed. Unfortunately motor carriers don't seem interested in taking him on with his lack of recent driving experience. Any suggestions or recommendations? Is he going to have to hold his regular driver's license for so long before a company will train him or are there ways around this? He's applied to two motor carriers so far but they don't seem interested in taking him on. One is TMC. The other I'm not sure about

 

Three years since his license expired but he's been driving regular cars since his dad let him drive the farm truck on the farm as a kid 30 something years ago. He will need to go through a CDL training program but the companies he has talked to thus far are making it seem like the three year gap in driving is a problem. As far as I know he let it lapse because he was living in a city with abundant public transportation options but that's no longer the case since he's moved
