I applied in-person. The process took 1+ week. I interviewed at Optima Engineering (Charlotte, NC) in Jan 2022
Interview
The interview went well meeting with the CEO and department head. I don't remember anything specific about it. My big disappointment was not being informed as to who would be supervising my work, I'd assumed it was the people I met with, but it was not. I'd recommend asking who will directly supervise you and insist on meeting them. Asking what 'team' you'll be on is another way to ask the same question.
