Sun Nuclear Software Engineer interview questions

Process started with emails asking several base questions, including: desired pay, years experience, % working front end web development, experience with certain tools, Web API/restful experience. Followed a week later with a phone call with 2 people. Phone call went very well and they wanted to proceed forward with a code presentation. This is where the interview process ended as I was unable to present code (no personal project, and company code is NDA).
