Xinyx Semiconductor interview questions

For technical interview, just basic CMOS and logic gates question. When I applied a few years ago, I had a panel interview wherein there were 2 senior engineers asking questions. They have set of questions but there were times that they asked a follow-up question from my answer. My technical interview lasted around 1-1.5hrs. The duration of my interview is because of a follow-up question that took several minutes of discussion and another set of follow-up questions.
