Before interviewing the company, I'm always quite nervous as I do not know what the interviewers will be doing in the session, and their processes. Questions like... "How many rounds?" "Are the interviewers friendly and respectful?" "What kind of interview questions did they go for?" "Leet Code questions?" "System design questions?" etc.

You could also add a upvote & downvote method / reply feature so that other people could discuss & confirm their experiences as well.
