I applied online. I interviewed at Challenger (Houston, TX) in Aug 2016
Interview
On line applying, took two weeks and first interview about political view and a kind of IQ test. One week later got call to take the second interview. Three or four weeks passed, but not any offer yet.
I originally had an Informal Zoom Meeting, This was followed by a Formal Technical Interview, The final Interview was with senior managers to check my motivations for working in the role. It was a relatively quick and simple process with detailed questions.
