First, I provided a brief introduction of myself. Then, I answered some basic Verilog questions based on given code (no coding was required). I was asked to walk through the JTAG/TAP state machine with a given input. (The interviewer had instructed me to review basic JTAG/TAP architecture a few days prior).

Next, there was a super simple coding question, followed by a problem-solving question designed to assess my approach to tackling challenges.

Write code to detect prime numbers.
