Assume a North American STEM-based tenure-track position to which a search committee, including a couple of faculty members and the chair of their department, corresponds.
Regarding decisions to be made at various stages such as "initial shortlisting", "campus visit applicant selection", and "final selection", are all the cited decision making processes for such a tenure-track position totally transparent to all members of that search committee? In other words, which scenario described below (or otherwise) is the typical case?
Each member of the committee communicates their opinion about each applicant directly to the chair, and the other members do not know about the specific content of the assessment of other peers. Then, the chair, considering all the recommendations, solely selects the applicant who is the best in their estimation without expressing any justification to the remainder of committee members.
All members of the search committee can see each other's votes, and the chair shares their final justification to pick the lucky applicant(s) at every stage.
