Coding Technical
The first interview with Lutron was a 60-minute video call. It had two problems. The first was a coding question to see if you can tell the difference between pass-by-value and pass-by-reference. The second problem was to create a Rectangle class, and then add an undo function. After that, I had to add functionality to the class to track its state. Then, I was asked about inheritance so that other shapes could be made. Lastly, I was asked what would need to change in order to allow an undo function to undo the last modified shape, not just an undo relative to one function.

- The first interview with Lutron was a 60-minute video interview. The interview consisted of two problems: 1) What will this code print? It is question seeing if you can tell the difference between pass-by-value and pass-by-reference. 2) Create a Rectangle class in whatever language you wish. The point of this problem is to show that you can make a class. Then I was asked to include a undo function. I then had to add functionality to the class in order to track the state of the class. Next, I was ask about how would do inheritance so that there could be other shapes. Finally, I was asked what would need to change in order to allow an undo function to undo the last modified shape, not just an undo relative to one function.

Technical Coding
So they first looked over my resume. And then, while I was talking about my resume, the interviewer asked some questions. These questions were mostly about the stuff that seemed related to the job and also the parts I talked about in more technical detail. After that, we did one LeetCode easy problem. The interviewer kept making the problem more and more complicated as we went on.
