I applied online. The process took 4 weeks. I interviewed at Hawk-Eye Innovations (Atlanta, GA) in Feb 2020
Interview
One full day of tasks with a group. They did provide lunch and the tasks were somewhat enjoyable (puzzles of certain varieties), and we split into multiple subgroups for the different tasks. Then we each individually took a written test.
Interview questions [1]
Question 1
The tasks were all problem solving related, and the written test was a problem solving test.
