Two candidates for software roles at Lutron describe interviews that lean toward design thinking more than algorithm speed. One candidate for an associate application developer role reports a first round with an easy and a medium LeetCode-style array question, including removing duplicates from a list, plus standard behavioral questions answered in STAR format. Time and space complexity and a clear explanation of the code were part of that round. The same candidate describes a second round of about two hours that mixed low-level design with behavioral questions. The design prompt was a scheduler, where the candidate had to sketch the UI/UX and then either write the classes or draw a table schema.
A software engineer candidate describes a different format: a 60-minute video call centered on object-oriented design. It opened with a pass-by-value versus pass-by-reference code-output question. It then moved to building a Rectangle class in any language, adding undo, refactoring for inheritance across shapes, and finally making undo work globally across all shapes. The candidate found the interviewer collaborative and said the focus was how they handled evolving requirements.
A firmware engineering intern also reports C pointer tracing and hardware-flavored puzzles. That is a different role, so treat it only as a hint that Lutron interviewers may value clear reasoning about real-world systems. Both software candidates reported not receiving offers, so prepare thoroughly. Practice array and duplicate-removal problems, then rehearse extending a small class design step by step while explaining trade-offs aloud. Keep STAR stories ready.

Synthesized from candidate reports. Individual experiences may vary.
One candidate reports a first round pairing an easy and a medium array question, including removing duplicates from a list, with behavioral questions. They were asked for time and space complexity and an explanation of their code. Candidates should typically be ready to talk through their approach and to answer STAR-style questions.
A software engineer candidate reports a 60-minute video interview that began with a pass-by-value versus pass-by-reference output question. It continued with building a Rectangle class, adding undo, supporting inheritance for other shapes, and then making undo global across shapes. Expect requirements to be layered on, and explain your design trade-offs as you go.
The associate application developer candidate describes a second round of about two hours combining low-level design with behavioral questions. The design task was a scheduler: sketch the UI/UX, then write the classes or draw a table schema. This format may vary by team and role, so prepare to design under open-ended requirements.
