I was contacted by a hiring manager via email, and we set up an hour-long phone screen about a week later. I was asked a bunch of questions about DRC methodology, even though my expertise was in LVS. I was able to answer them fairly well, though, and was told I should get an invitation for an on-site interview. It took a couple of weeks, but I got the interview. After a mild amount of confusion between myself, the hiring manager, and the HR folks, I got the date straightened around. They paid for the entire trip, and booking it was easy and smooth.

The interview was a round-robin style with people in the department I'd be joining. I did not find it too difficult. Some of the job descriptions were about things that were not on my resume, and they asked me briefly about those to see what I knew but did not press me. They focused on discussing topics related to what was on my resume (physical verification and some scripting) or general problem-solving issues. It went pretty well, and a few of the engineers were enthusiastic about me joining the team.

I received an offer about three weeks after the interview. I did get positive feedback from the hiring manager within a couple of days, though.

Nothing really. Some pros and cons of different physical verification tools, how to filter through 100k+ errors, and how to solve chip-level LVS issues. Should be easy for experienced engineers to answer.
