I applied online. The process took 3 months. I interviewed at Zebra Technologies (Lincolnshire, IL)
Interview
It's a rigorous process!!! The interviews were 3-4 hours long and I had 3 interviews. End to end process took weeks. I felt like I was applying to work for the FBI or something.
Interview questions [1]
Question 1
I wouldn't really say there was a most difficult question. There were just a lot of them from multiple individuals within the organization.
