Yes, there are specific requirements for whether a US visa applicant receives an interview. These are specified in US law and in the Foreign Affairs Manual which is the official guidance for US State Department employees on how to do their jobs.
9 FAM 403.5 covers visa interviews and you may wish to read it in its entirety. It specifies the conditions under which an interview can be waived. It also specifies the conditions under which an interview cannot be waived, but that section is not unclassified and therefore not publicly available. It is certainly possible, because at least some of these conditions are based on local or regional threat intelligence, that conditions may vary from one consulate to another.
