Umop,
In any HR interview, you do want to know as much about the questions as possible, and if you have no specific info, prepare for as close to anything as you can. Good interview prep involves having as many specific, appropriate responses to as many HR questions as possible. The last thing you want to be doing is tackling a difficult question (such as "give us an example of a time you deliberately disregarded SOP") without prior preparation.
I have no idea what the Qlink interview is like, but the principle holds for all interviews and levels of question, from "tell us about yourself" to the really tricky ones.
