I do know someone who ended up at IBM Research from my lab. He was collaborating with them for his research before he graduated so I'm not sure if he even had to interview after finishing.

According to Glassdoor, Facebook research candidates are given the typical interview questions as part of the process: https://www.glassdoor.com/Interview/Facebook-Research-Scient...

Same at Google: https://www.glassdoor.com/Interview/Google-Research-Scientis...

For what it's worth, though I've never particularly sought out a research position in industry, I haven't really come across too many listings which leads me to believe the positions are few and far in between.
