WD Electronics Engineering Design(PCB Layout) Intern interview questions

I got an interview notification approximately two weeks after I submitted the application. The entire interview process contains two round. First round was a phone interview with HR and the second round was an online interview with 3 engineers. The phone interview was chill. HR asked me questions related to my academic work and my experience in PCB design. The second round interview allows me to have a chance to get to know about the their PCB designing team. They asked me some detail/process about PCB designs and also asked me about my experience working with PCB(but in more detail).
