It was pretty straight forward with the typical questions. Optical knowledge isn't necessary because they will train you. But it doesn't hurt. Had to interview with one of the owners.
I applied through an employee referral. I interviewed at SEE Eyewear
Interview
It was pretty painless. Like most companies, they find many employees by current employee referral. Since I was referred and had plenty of experience, my interview was pretty much just an opportunity to meet the manager and discuss availability.
Interview questions [1]
Question 1
They asked me about my optical experience and previous work experience.
Manager that interviewed was very friendly. He didn't ask the typical interview questions everyone asks. I got called back that night to get started with the hiring process. It was easy going and a quick process.
