I applied online. The process took 4 weeks. I interviewed at Amtrak (Washington, DC) in Dec 2018
Interview
A recruiter quickly contacted me via email. We set up a phone interview with 2 of the lead ITs. Asked very simple technical questions. Set up an on site interview, had more technical questions. Discusses past professional experiences. Said they would follow up afterwards.
