I applied online. The process took 2 months. I interviewed at Kelly Services (Durham, NC) in June 2019
Interview
Easy, asked about Bluetooth and Customer Service questions. Can't remember the rest but pretty atarigjt forward. They may have changed it by now but it still shouldn't be too difficult if you have Customer and some technical support background as well
Interview questions [1]
Question 1
Where do you go to turn Bluetooth on and off in a mobile device
