It’s annoying. Having said that, I am afraid it’s somewhat typical
In my experience that’s a pretty typical expectation of a presentation in front of peers, samples of work and some type of questionnaire (often times more than one, additional is a psychological type of questionnaire in addition to professional one). I think often times what’s in resume or LinkedIn just isn’t enough.
I’ve been on interview teams where people lied or exaggerated on their resumes and things didn’t match or they were unable to present anything despite things they wrote. Not saying it’s the case with you but they don’t know you.
Also more money gets paid and higher the position more additional stuff they will require. I’d say for a director role these things seem to be a rather typical expectation. They’d not want to bother just going by what’s in the resume. If they have 5 people with similar resumes, they’d like to see more stuff to even get bothered
