Is this Normal

[kaydrew]

I am in the process of applying for phd programs. I've submitted several applications so far and one university has requested a bibliography, another writing sample, chapter breakdown of my thesis, and a literature review prior to inviting me to a Zoom interview. Is it normal for schools to request a literature review and chapter outline prior to an offer of placement/acceptance into the school? So far, none of the other programs have made this request. I assumed the literature review came while writing the actual dissertation.
