Lutron Electronics Embedded Software Engineer interview questions

Applied online. They sent an email scheduling an interview with a senior employee. During the interview he first talked about the company and then went into the technical part of the interview. Where it was mostly OOP type questions and pointer manipulation. Everything was done was on this live notepad website, no IDE, he would copy and paste your code to see if it would run. Very nice guy, however, I am not the best programmer, mostly a hardware guy. Did not allow me to write on a piece of paper, cameras on, does not record your screen.
