You need to leave a voicemail to answer seven questions the company sent via email. The voicemail is about 3 minutes. And then you give 2 references of yours to start the process. Until they call you up, no personal contact or interaction gets involved.
I applied through an employee referral. The process took 1 week. I interviewed at StarQuest (Chicago, IL) in Oct 2017
Interview
StarQuest was very accommodating. They interviewed in three different cities throughout the U.S. Chicago, New York, and Raleigh. I was unable to make it to the Chicago interview due to time constraints from my previous job, however they were willing to conduct an online interview utilizing Zoom.
