I applied online and the process took about a month. There were a total of two interviews consisting of technical and behavioral rounds. The first interview was with a Software Engineer at Lutron. I had to program multiple solutions (iterative and recursive) for the FizzBuzz problem, and I was asked questions based on the code that I had written. The second interview consisted of two parts. For the first part, I was interviewed by two engineers, and I was asked to design the UI for a schedular app. I was asked questions about the design choices that I made and I was asked to design a database for storing all the information for the app. For the second part of the interview, I spoke to two other engineers at Lutron and they had me do a role-playing exercise where I had to pretend like I was an employee at Lutron and I was given a problem to solve.
