I applied online. I interviewed at Lutron Electronics in Apr 2021
Interview
Had a few different types of interviews that was conducted through zoom, the interviews were both technical and behavioral. The first interview as more basic and the second interview had 2 parts with one being technical and one being behavioral.
Interview questions [1]
Question 1
Asked me to analyze a circuit and to find which light was the brightest or if enough current was reaching something.
I applied online. The process took 3 weeks. I interviewed at Lutron Electronics (New York, NY) in Jan 2023
Interview
The first interview was a technical interview where I solved several problems. The problems were moreso about explaining my process to find the solution and what I was thinking about while solving it. While I didn't personally have any issue with the problems, one of the things the interviewer expressed was that some skills were use it or lose it, and many electrical engineers tend to gravitate towards embedded programming. I have not yet gone through the second round of interviews.
Interview questions [3]
Question 1
A circuit is given with a resistor divider feeding a capacitor, which is connected at time t=0. The problem asked to plot the output voltage on the capacitor
The power supply feeds a microcontroller. The minimum and maximum voltages are given, and the microcontroller is typically in asleep state and occasionally wakes up to send RF signals. The current consumed in both states is given. Are the supply voltage requirements violated?

Interview
Too long of a process and it was mentally draining.
1st Round: 1 hour interview with technical questions. RC circuit analysis along with voltage-time graphs of cap.
2nd Round: 2 1.5 Hr interviews that were extensively exhausting. First interview was technical including light bulb question in series. Which has more power. Then a BJT question with capacitor. Second interview was a customer service role-play which was really odd.
Overall, the first round interview was fun but to have a 3 hour 2nd round interview is exhausting and apparently theres a 3rd round for another 3 hours. They decided to not continue with my application after the 2nd round.
