You're being downvoted but I've had the same experience as well. They bias interviews that are supposed to be performance based.

Resumes are a carefully crafted signal paper targeted at getting past an algorithm, recruiter, and into an interview. They're chock full of brand names (both education and company) and keywords. There's also unconcious bias based on the person's last name, locations that they've lived in the past, and so on.

I've found the best thing to do is skim their past job roles, to set expectations for where you can start with the level of difficulty in questions.
