Behavioral Technical
It was a pretty straightforward interview, with a mix of behavioral and technical questions. They were interested in how I would approach designing a shelf, specifically asking about the design process itself and any potential failure points. They also asked about the general stages involved in mechanical design.

Technical
The interview lasted about an hour and was a technical interview, even though that wasn't stated beforehand. It was a pretty chill and nice chat. I had to draw on a digital whiteboard and answer questions about engineering stuff.

- Can you explain the different modes of heat transfer?
- For example, how does heat transfer from a coffee cup?

Behavioral Technical Coding
First I spoke with the hiring manager, who has been at Lutron for over ten years. This was to discuss my background and what the job entails. Then, there was a technical interview where two engineers and I tackled some electrical and mechanical problems related to Lutron's products, involving digital whiteboarding and calculations. This was followed by a peer interview with someone at a similar level, and then an interview with management. Overall, the process was well-organized and more technically challenging than other interviews I've had, though the manager seemed a bit unprepared, which was unusual.
Confirmed questions2 questions
- Given a diagram of a lighting circuit, can you identify its components and explain their characteristics?
- Regarding a photo of a dimmer switch, which part is primarily responsible for heat generation?
