Cisco Sr Asic Design Verification Engineer interview questions

Had a phone call with recruiter after applying to the position . Hiring manager of the team scheduled a 1 hr interview . He asked me to write code from base test to sequence, drivers on whiteboard and you shouldn't miss a thing in that code. Instead of asking about different verification scenarios and issues I found in my past projects, it was more like coding on a notepad. FYI, I moved to IDEs a long time ago and don't remember the syntax.
