Codeplay Software Computer Vision Engineer interview questions

I was request to provide the code of one or more of my project. After one week I receive an e-mail to set the interview date. This interview was with the CTO and a senior developer, they were interesting in my personal profile and ask me about my CV. They ask my about the project which I provided and I also was asked to revise come code in C++. The second interview was with the CEO and two senior developers, this was similar to the first one.
