If I can, yes. But many interviewees are not prepared for that, and I've had to adapt to that.
If you are interviewing, please by all means bring samples of your work and be ready to discuss them, if you possibly can. But some people come from places where they can't talk about what they did (like, literally, Federal law in some cases), or for some other good reason can't really substantiate what they did.
You also have to account for the fact that a lot of the ways of finding out what they did in the past are somewhat unreliable. Many past employers have their own reasons for not being forthcoming or entirely truthful. The interviewee is incentivized to exaggerate their claims. In this context it's hard to get very much solid information of the type you're asking for.
My preference is to see past accomplishments, then use the interview to substantiate that they are indeed your accomplishments and you were not just generally in the area of accomplishments that happened to be occurring. But alas, that's not always an option.
