The interviewer was really nice and guided my through the problem when I got stucked. I didn't feel like I can pass, but I recieved the invitation of HR call. But just several days before the call, they called me and said they have already fill the spots. Soooo sad!
Interviewer asked questions about stuff on my resume, shared background about Lutron, did one technical question that got increasingly difficult, then allowed me to ask questions. Overall, not super intense process
