Analog Devices interview questions

I was interviewed for Digital Design internship. Interview was of 2 rounds followed by HR round. Was asked a lot of logical/aptitude questions in addition to basic digital logic and verilog

1st round is written exam of basic analog question and ckt theory.then analysis of test paper with interviewer.once you qualify written then only f2f interview will happen.i have done lots of silly mistake.question was average level.
